Description

Hard-kill-linked small unmanned aerial vehicle jammer {JAMMER FOR SMALL UAV INTERLOCKED WITH HARD-KILL}

The present invention relates to blocking and protection of wireless communication, and more particularly, to a jamming system that operates in conjunction with a predetermined destructive hard-kill means and can detect and effectively neutralize air intrusion of small unmanned aerial vehicles.

A jammer is a type of jammer and refers to a device that detects a direction when a threat is detected and then oscillates a certain frequency in the direction of the target to neutralize it.

Recently, with the development of drone technology, various types of drones have been developed and supplied to the public. International companies like Amazon and Google are in the process of commercializing drones that can perform a variety of tasks, from delivering goods to providing high-speed Internet access. These drones can be seen as a type of unmanned aerial vehicle, which is smaller and lighter than military drones, which means that detection is relatively difficult. Due to the spread of these drones, drones, which are low-cost unmanned aerial vehicles, are becoming a potential threat to commercial aviation facilities, essential infrastructure, confidential facilities, and even the military. In other words, since the possibility of misuse always exists depending on the combination of drones with photography or video recording equipment, there is a possibility of becoming a threat to various security facilities or social infrastructure. In fact, in Washington, there is a case where a person who enjoys drones as a hobby accidentally crashed inside the White House and a security alert was issued. There is also a case where a request was made to develop a weapon that is available. In addition, in Korea, the need for so-called anti-drone defense facilities that can prevent intrusion of aircraft into the no-fly zone has emerged after the incident in which a North Korean drone crashed while filming the Blue House and downtown Seoul.

However, domestic as well as worldwide development of equipment capable of effectively responding to the intrusion of unmanned aerial vehicles that operate by receiving frequencies from the air, such as drones, is still quite insignificant.

On the other hand, wireless communication networks used in drones transmit radio waves to the air so that information can be exchanged in various forms such as one-to-one, many-to-one, and one-to-many. This is called wireless communication jamming.

Korean Patent Publication No. 1999-0083728 discloses a jammer of the prior art, and FIG. 1 is a block diagram thereof.

Looking at this, the oscillation signal from the oscillator 10 is transmitted to the upconverter 40 via the buffer 30. In the upconverter 40, this oscillation signal is frequency multiplied and up-converted to the frequency band of the wireless communication device to be disturbed. In order to prevent the upconverter 40 from free running when power is applied to the device, the power-on reset unit 20 turns off the upconverter 40 after a certain period of time has elapsed after power is applied. It acts as a reset.

However, with the recent diversification of attacks on national defense and security facilities, various attack methods are converged on various types of drones, and thus, defenses are limited only by conventional anti-aircraft fire systems or independent jammers.

The present invention has been devised to overcome the problems of the prior art, and it is possible to detect and track penetration into the air, while hard kill and soft kill can be operated in conjunction, so that efficient response is possible. It is an object of the present invention to provide a jammer for unmanned aerial vehicles.

The present invention to solve the above problems is an antenna unit 1500 that transmits jamming waves, a spoofer unit 1200 that generates and transmits a spoofing signal to the antenna unit, and a jammer unit 1100 that generates and transmits a jamming signal to the antenna unit. ) including an oscillation unit 1010, a selection unit 1001 for selecting the operation of the spoofer unit and the jammer unit, an image management unit 1800 for expressing an image signal from the video equipment unit to an imaging device, and a hard kill control device. and a main controller unit 1700 that controls the oscillation unit in conjunction with the hard kill equipment unit and the video equipment unit, and provides a hard kill interlocked small UAV-compatible jammer.

The image management unit displays the detection display unit 1810 for the detection area when the operation of the hard kill control device starts, identifies the target in the main controller unit, and emits the target image 1811 and the antenna unit in the shooting preparation step. It is preferable to display the radiation display unit 1820, which is an area, and visualize and display the output according to the distance of the radiation display unit in the shooting down step.

In addition, it is preferable that the image management unit displays the target image and the radiation display unit in conjunction with the map in the shooting down step.

The main controller unit can stop the control of the pan/tilt unit by the hard kill control device when the target image is moved in the soft kill mode during the shooting preparation step and is within the range of the radiation display unit.

In addition, the antenna unit is composed of a first antenna 1510 corresponding to ISM 2.4 GHz, a second antenna 1520 corresponding to ISM 5.8 GHz, and a third antenna 1530 corresponding to GNSS, switching unit 1300 can be selected from

The main controller unit may operate the oscillation unit by presetting an approaching distance and an output in a shooting preparation step when the hard kill equipment unit is moving.

According to the present invention, by integrating and operating hard kill equipment and soft kill equipment, which have conventionally been operated simply and independently, there is an effect that allows flexible response for each situation and dramatically improves the efficiency and reliability of anti-aircraft UAV defense.

Accordingly, it is possible to establish a plan for an organized anti-aircraft defense network, and thus, bombing threats to major national facilities such as nuclear power plants and airports, illegal filming of major national facilities, terrorism threats of VIP personnel, and threats of terrorism to stadiums or densely populated areas It can cope with terrorism threats, block the import of drugs and other substances, as well as cope with indiscriminate use in no-fly zones, and have an effect of preventing collisions with people or facilities in advance.

Hereinafter, with reference to the accompanying drawings, a hard-kill-linked small UAV-compatible jammer of a preferred embodiment according to the present invention will be described in detail.

However, the embodiments described below are only intended to be described in detail so that those skilled in the art can easily practice the invention, thereby limiting the scope of protection of the present invention. doesn't mean

In the following description, when a part is said to be 'connected' to another part, this includes not only the case where it is directly connected but also the case where it is connected with another element or device in between. In addition, when a certain part 'includes' a certain component, this means that it may further include other components without excluding other components unless otherwise stated.

Basically, the present invention includes an antenna unit that operates in conjunction with a hard-kill control system and transmits jamming waves, a video equipment unit that generates and displays a detection image for a remotely approaching target, and the antenna unit and video equipment. A pan-tilt unit for directing a target to a target, and transmitting a jamming signal or spoofing signal to the antenna unit, controlling the pan-tilt unit to direct the target generated by the video equipment unit, and displaying the output for each distance of the target Provided is a hard-kill-linked jammer for small unmanned aerial vehicles including a control unit.

In the present invention, an unmanned aerial vehicle such as a drone approaching through the air is described as an example of a target, but the target approaches the facility to be protected through the ground as well as through the air, and various types of devices that can be controlled or operated through frequencies to disturb It should be understood that these are included.

In the concept of the present invention, the efficiency of drone defense is drastically improved by convergence of a soft-kill system for jamming to neutralize enemies with frequency and a hard-kill control system for physical destruction. Here, the hard-kill control system is a surveillance unit. , It can be understood as including a trigger unit and a transfer unit.

For example, the hard-kill control system may mean a combination of RCWS (Remote Controlled Weapon Station) and Vulcan, wheeled anti-aircraft gun, mounted Vulcan, laser anti-aircraft weapon, etc., C2A (Command Control and Alert) or independent The defense system will be fused with soft kill technology.

2 is a configuration diagram for explaining the hard-kill-linked small unmanned aerial vehicle jammer of the present invention.

The antenna unit 1500 performs a function of transmitting jamming radio waves to a predetermined targeted area or location. The antenna unit 1500 may be selectively and additionally arranged with directional or non-directional antennas, and is preferably composed of a plurality of antennas so that a band can be selected according to a predetermined frequency range. Examples related to this will be described later.

In the present invention, it can be understood as including a jamming signal and a spoofing signal.

Jamming refers to a method of disturbing the enemy's radio reception by intentionally emitting, re-radiating, or reflecting noise or radio signals similar to noise for the purpose of interfering with the enemy's use of electronic equipment. Disturbances to the GPS signal can be considered. Spoofing refers to a method of sending processed fake information to a drone to force it to move to an originally unintended location or land, and may mean stealing an operating frequency or manipulating GPS. Additionally, the jamming radio may include a hijacking method of stealing the control function itself.

In the case of transmitting jamming waves to neutralize drones, for example, a frequency hopping method can be applied to disable a remote controller transmission/reception module or a spread spectrum method can be applied to disable remote controller transmission/reception.

At this time, the frequency band that can be applied to neutralize the unmanned aerial vehicle in the air is optional, but preferably GPS (1,550 MHz ~ 1,650 MHz), 2.4 GHz control frequency band (2,400 MHz ~ 2,484 MHz), 5.8 GHz control frequency band (5,150 MHz ~ 5,850 MHz) can be set to three bands. More broadly, the jamming frequency can be set in the range of 20 MHz to 30 GHz.

The antenna unit 1500 may consider a case in which a dual polarization antenna that simultaneously transmits vertical and horizontal polarization waves is applied as the broadband high-gain antenna. In addition, it is desirable that the gain and structure be greater than 10 dBi and that the beam width of the antenna be limited to within 30 degrees vertically and 40 degrees horizontally in consideration of radiation to the air and accuracy of remote radio transmission.

In the concept of the present invention, the antenna unit 1500 can be operated in conjunction with the hard kill control device. The hard kill control device includes the hard kill equipment unit 3100 and the video equipment unit 2100 as external equipment. can be configured.

The imaging equipment unit 2100 may perform a function of generating a video image of a target and location, transmitting the image to the control unit 1000, and imaging the image in the imaging device. In the embodiment of the present invention, the video equipment unit 2100 is described as an example of a radar device. Since the radar device is a device for measuring the direction and distance of a small unmanned aerial vehicle by measuring the time until a reflected wave is received using the linearity of radio waves, a detailed description thereof will be omitted. In addition, the video equipment unit 2100 may be configured to include a device such as a CCTV that generates image signals of various wavelengths such as visible light or infrared light.

In the description of the present invention, hard kill means an attack capable of physical and mechanical destruction, and may include various attack means capable of destroying a target drone with momentum or energy, such as a laser, as well as a machine gun or anti-aircraft gun. there is.

Basically, the hard kill equipment unit 3100 and the antenna unit 1500 can be directed to the target according to the image signal generation of the video equipment unit 2100 and the detection and tracking of the target by the control unit 1000. For this purpose, the pan/tilt unit 2200 may be coupled to move in conjunction with the video equipment unit 2100 and/or the antenna unit 1500 and/or the hard kill equipment unit 3100.

The pan/tilt unit 2200 has a pan function and a tilt function, and thus can rotate through two or more axes. As a preferred range of motion, the pan function is not limited to 360 degrees, and the tilt function can be set in the range of +90° to -10°. In addition, the rotational speed may be operated at 0.01 to 60°/s in the pan function and 0.01 to 30°/s in the tilt function.

The antenna unit 1500, the video equipment unit 2100, and the hard kill equipment unit 3100 may be coupled to a floor, ground or structure, but are not necessarily limited to the illustrated form. Basically, since it is preferable that the hard kill equipment unit 3100 and the antenna unit 1500 are directed toward the same target drone, it would be desirable to move them together by the pan/tilt unit 2200.

The antenna unit 1500, the hard kill equipment unit 3100, the video equipment unit 2100, and the pan tilt unit 2200 can transmit and receive predetermined detection signals and control signals to and from the control unit 1000, and the illustrated examples and As such, it may be disposed in a separate configuration, for example, mounted in a vehicle, and in some cases, a case in which the antenna unit 1500 and the control unit 1000 are integrally configured may be considered.

In addition, the antenna unit 1500 and the hard kill equipment unit 3100 do not necessarily have to be disposed together. can work in tandem.

The control unit 1000 receives a predetermined image signal from the video equipment unit 2100, identifies a target, controls the pan-tilt unit 2200 to track it, and generates a disturbance frequency for interception according to a predetermined distance to the antenna. It may be possible to send a call from the unit 1500, and specific embodiments in this regard will be described later. However, as will be described later, if an image tracking system is built in a ready-made hard kill control device, the control unit 1000 suffices if it operates in conjunction with it, and generates a disturbance wave according to a predetermined integrated control signal and transmits it as an appropriate output. will be able to do

3 are diagrams showing images implemented in an imaging device according to the concept of a hard-kill-linked small unmanned aerial vehicle jammer according to the present invention.

Normally, the effective range of the jamming wave may be narrower or shorter than the area where the video equipment unit 2100 can detect and track due to problems such as power for generating and oscillating a frequency transmitted from the antenna unit 1500 and weight of the equipment. can be understood as

In an embodiment of the present invention, it can be understood that the effective range of the jamming wave in the antenna unit 1500 is within 4 km. However, the distance may be optional depending on the type of equipment or the environment.

It is as described above that the hard-kill-linked small unmanned aerial vehicle-compatible jammer of the present invention can be operated in conjunction with the hard-kill control device, and the following images visualized on the imaging device will be described in order.

In the illustrated example, it is visually implemented by the detection radar, and description of image implementation of the known radar will be omitted.

(a) of FIG. 3 shows a time point at which the detection radar starts to operate and the drone starts to be detected. For example, it may be a display screen of a fire notification device in an independent defense system, or a screen displayed in a C2A system. In this case, the user's selection may be to turn on or off the detection radar, and an embodiment of control related thereto will be described later. In the drawing book, two target images 1811 are created in the north-north-east direction and are relatively far away from each other.

(b) of FIG. 3 shows a situation in which tracking is performed at the point in time when fire control is initiated. A predetermined area in the direction of the target image 1811 is set as the radiation display unit 1820, and the radiation display unit 1820 is fan-shaped with a predetermined angle, which is jammed by the jamming radio wave reached by the antenna unit 1500. This may be a possible area. For example, when the switch is turned on at the start of a hard or soft kill operation, the terret exhibits a forward radial direction of 10° to 30°, and similarly, the hard kill equipment unit 3100 and the antenna unit 1500 direct it together. do. Here, since the hard kill equipment unit 3100 is aimed with a line, the aiming line of the hard kill equipment unit 3100 will follow the central angle of the range of the radiation display unit 1820. If the target image 1811 is moved during this tracking process, the radiation display unit 1820 may move together. can

When a target, that is, the target image 1811, appears within the range of the radiation display unit 1820, it is possible to neutralize it by radio waves, so there is no need to control the operation of the pan/tilt unit with a hard kill control device. In this case, when the target image 1811 approaches the set area or border line of the radiation display unit 1820, the hard kill control device may operate the pan/tilt unit 2200.

3(c) shows a state in which the soft kill is operated, and when the operator presses a predetermined radiation button, the radiation display unit 1820 in the imaging device can display the size of the output in each distance unit as an image. In the drawing, it is an example in which four areas for each distance are expressed in different colors (Pa, Pb, Pc, Pd) for each output. The farther the distance, the weaker the radio signal.

It is preferable for intuitive response that the display of the target image 1811 displayed on the imaging device, the radiation range, and the output is performed in conjunction with a map, not just a simple radar image.

Figure 4 is a block diagram for explaining the control unit in the hard-kill-linked small unmanned aerial vehicle jammer of the present invention.

The control unit 1000 may include an oscillation unit 1010 that generates and transmits a jamming signal to the antenna unit 1500, receives an image signal from the video equipment unit 2100, and visualizes it in the video equipment. It may include a video equipment unit 2100 that performs information processing on target detection, identification, tracking, and interception, and a main controller unit 1700 that controls interlocking operations with the hard kill control device 3000. there is.

The oscillation unit 1010 may generate a jamming wave by including a signal generation unit, an upconversion unit, an amplification unit, a filter unit, etc. is described later.

The image management unit 1800 receives image signals generated from the image equipment unit 2100 such as a radar, converts them into data, and performs a function of visualizing the detection display unit 1810 as shown in FIG. ), the radiation display unit 1820, and visualization representation of the output may be performed.

In the present invention, since it can be operated in conjunction with an existing independent hard kill control system or C2A, the operation of the oscillation unit 1010 can be achieved in conjunction with the operation of the pan tilt unit 2200.

This main controller unit 1700 can be operated through independent power supply and control, but in the present invention, since it operates in conjunction with the hard kill control device 3000, it is provided with a communication unit 1900 and The communication unit 1900 may perform tracking and management in conjunction with the operation of the hard kill mode by the hard kill control device 3000 and movement by pan-tilt in a wired or wireless manner.

Meanwhile, referring to FIG. 3 , the main controller unit 1700 may perform a function of identifying a target drone entering a predetermined detection area in the detection unit 1710 based on the image signal of the video equipment unit 2100. there is. At this time, it is possible to identify a target that needs to be neutralized and a target that is not a target through factors such as the size or frequency of a predetermined reflected image.

The detection unit 1710 may identify a target among moving objects through various image algorithms. For example, a standard for the size of the target may be 300 mm × 300 mm or more. In the case of a small drone of 300 mm or less, remote control for outdoor long distances and high altitudes is virtually difficult, so in this case, shooting or threats to certain facilities can be excluded. However, the standard for the size may be set in various ways. In addition, the detection unit 1710 may identify a target in comparison with predetermined shapes by preparing a criterion for a shape in addition to a criterion for a size.

The tracking unit 1720 may identify a target among detected objects and cause the pan/tilt unit 2200 to start tracking. In the present invention, since the radiation range has a predetermined area, when the target image 1811 moves within this range, a request signal can be transmitted to the hard kill control device 3000 to limit the movement of the pan/tilt unit 2200. . When the target image 1811 is adjacent to the set boundary line or area of the radiation display unit 1820, the pan/tilt unit 2200 may be operated so that the target image 1811 is positioned at the center line of the radiation angle. Control in this case will correspond to hard kill aiming.

In addition, the output unit 1730 may set an output according to the distance, visualize and display the output with video equipment, and control the output of a predetermined amplifier in comparison with the distance to the detected and tracked target.

On the other hand, the interlocking unit 1740 modifies the control of the movement of the pan/tilt unit 2200 or the hard kill operation such as triggering or reloading of the hard kill control device 3000 for interlocking operation with the hard kill control device 3000. can perform a request, and the antenna unit 1500 can be operated in conjunction with the above operation. For example, when the wheeled Vulcan device is set as the hard kill equipment unit 3100, it is necessary to lower the sensitivity to the position of the target image 1811 that changes during the movement process, so at least in the case of soft kill operation The operation of the pan/tilt unit 2200 may be suppressed within the radiation angle range of the radiation display unit 1820. In addition, when the wheel-type hard-kill equipment is moved for proximity to the target, the required distance and output settings may be performed in advance, and the launch unit 1010 may be prepared. In this case, since physical tracking and defense through jamming propagation can be performed simultaneously, the efficiency and speed of response can be improved.

5 is a configuration diagram for explaining a frequency management system for a jammer corresponding to a hard-kill-linked small unmanned aerial vehicle of the present invention.

The oscillation unit 1010 is connected to the antenna unit 1500, includes a predetermined signal generation unit, an up-conversion unit, an amplification unit, and a filter unit, and can be controlled by the main controller unit 1700 as described above. Since well-known configurations such as Registered Patent No. 10-1969431 owned by the applicant may be applied to the elements and elements for generating the signal of the jammer, a detailed description thereof will be omitted.

However, referring to the control unit 1000, in the present invention, a selection unit 1001 may be further configured to select a predetermined mode, and the selection unit 1001 receives an operator's selection for spoofing and jamming operations. You will be able to.

Accordingly, the spoofer unit 1200 and the jammer unit 1100 may be combined, and the spoofer unit 1200 receives a predetermined frequency input from the GNSS antenna.

Each signal generator (reference number not indicated) may generate a radio wave blocking signal, and as will be described later, may perform a function of sweeping two or more signals into an intermediate frequency (IF) band. The frequency band may be selected by the user and input through the main controller unit 1700, and may be a frequency band sensed like the GNSS antenna.

At this time, as described above, one or more Direct Digital Synthesizers (DDSs) and/or Field Programmable Gate Arrays (FPGAs) may be selected and combined to generate two or more signals. The signal generator can generate a jamming signal using white noise. As will be described later, it can be composed of individual signal generators to generate independent signals for each channel, and in some cases, individual signals corresponding to the number of channels. It may also consist of a signal generator. As described above, the band applied here is preferably the GPS and/or ISM 2.4 GHz band and/or the drone control frequency band and/or the ISM 5.8 GHz band.

Accordingly, the antenna unit 1500 may be formed by combining a first antenna 1510 corresponding to ISM 2.4 GHz, a second antenna 1520 corresponding to ISM 5.8 GHz, and a third antenna 1530 corresponding to GNSS. And, the switching unit 1300 will be able to select each oscillation in the communication band and the GPS band.

In addition, the control power controlled by the main controller unit 1700 may be supplied from the power supply unit 1600. The power supply unit 1600 may be configured as a power supply unit (PSU), and in this case, For a stable supply of power, it may also be considered to be connected to a battery unit or a main battery of a wheeled device.

The up-conversion unit receives predetermined DC power from the power supply unit 1600 and up-converts the signal of the IF band generated by the signal generator to the RF band, which is a guard frequency band. The upconversion unit 1200 functions to upconvert the IF frequency generated by the signal generator 1100 into a commercial frequency band.

The up-converter converts the carrier signal of each channel generated by the signal generator into an RF frequency band of a predetermined band.

The amplification unit receives predetermined DC power from the power supply unit 1600 and amplifies the signal output from the upconversion unit. A power level of a signal output from the amplification unit may have a higher power level than a power level of a signal of a band to be disturbed. This output may depend on the control of the output unit 1730.

In addition, the filter unit suppresses the unwanted signal of an unwanted band among the signals output from the amplification unit, selects only signals within a designated band, combines them as jamming signals, and outputs them to each antenna of the antenna unit 1500. function Such a filter unit may function to reduce the effect of interference on adjacent frequencies caused by the output frequency of the amplification unit.

When a frequency band desired to be disturbed is selected as described above, the main controller unit 1700 may select an input for the selection. However, in the present invention, when neutralizing an unmanned aerial vehicle, it is also considered that the main controller unit 1700 presets the frequency bands of GPS and ISM as input frequency ranges, combines them in a wide band, and transmits them to the antenna as a single output. I can try it.

As described above, it is desirable that the power level of the signal output from the amplification unit has a power level higher than that of the signal used in the target to be disturbed. It was confirmed that it could be blocked.

Meanwhile, the main controller unit 1700 may be wired or wirelessly connected to a control unit such as a console type to monitor a predetermined state and control functions.

6 is a diagram for explaining a case of customization for each step according to an embodiment of the present invention.

The illustrated items may be understood as images or selection switches of video equipment that are basically customized.

The control start unit 1910 corresponds to the detection step, and basically, the operation of the video equipment unit 2100 can be selected to be ON/OFF. When the image equipment unit 2100 is formed of a radar, it corresponds to the start of radar detection in all directions, which is basically performed by monitoring the operation of the hard kill control device 3000.

As shown in (c) of FIG. 4, when a target is detected and the area of the predetermined radiation display unit 1820 is displayed and fire control and preparation are completed, the operator can select two options. The selection is input to the selector 1001, and can be basically divided into a mode selector 1921 and a band selector 1922. The mode selector 1921 selects between a jamming mode and a spoofing mode, and in some cases, a hijacking mode may be added.

In addition, the band selector selects a band and an antenna from among the GNSS signal, the ISM 2.4 GHz signal, and the ISM 5.8 GHz signal. In the illustration, the GNSS signal and the ISM 5.8 GHz signal are ON, and the ISM 2.4 GHz signal is OFF. This may be related to the management of overall output and power.

7 and 8 are graphs illustrating examples of disturbance frequency signals.

As described above, when jamming radio waves are transmitted to neutralize drones, the frequency hopping method can be applied to sweep or the spread spectrum method can be applied to disable remote controller transmission and reception.

In the case of FIG. 7, a jamming wave is generated by spreading the spectrum, and AWGN noise is generated using a Spread Spectrum Generator and the space is minimized. Thus, the influence of the environment can be minimized.

8 is a graph showing output characteristics selectable by the selector.

As described above, in the present invention, a plurality of CW signals sweeping a set band may be included. For example, when jamming is performed on a 5G signal, a 1-tone first CW signal for a predetermined band is generated, and a plurality of second CW sweep signals of continuous wave channels corresponding to a plurality of synchronization signal blocks within the corresponding band are combined. The second CW sweep signal is individually turned on/off, so it can be easily changed when the synchronization signal block frequency is changed, and the difference in strength between the first CW signal and the second CW sweep signal is determined for the purpose of jamming the original service signal. It would be better to keep it large.

As described above, in the present invention, jamming waves can be generated in all communicable bands (20 - fe n), and frequencies for each band are classified as bands, and selection and jamming method control is possible.

Referring to (c) of FIG. 8, the frequency generator selects a spot jammer mode as a first mode, a sweep jammer mode as a second mode, and a third mode according to selection by the selector 1001. As a mode, Barrage Jamming Mode can be selected.

Regarding the sweep of the frequency, a description overlapping with the above will be omitted.

Accordingly, editing for each frequency band is possible, and multi-tone jamming support by multi-carriers as well as a single tone is possible. As described above, it should be noted that there is an advantage of being able to immediately adapt to SSB frequency fluctuations because on/off is possible for each channel. In the case of the concept of the predetermined multi-tone jamming described above, it is externally generated through a signal generator, which is basically a combining generator, and the multi-tone signal generated in the baseband is output to the IF band, and the RF unit 1200 uses the commercial frequency band It can be operated so that transmission is performed by upconverting to , and as another embodiment, a jamming signal may not be generated in the baseband and may be directly generated in the IF band to achieve structural simplicity.

At this time, it is possible to control the sweep interval and sweep time of the jamming signal, and to control the intensity of the output for each jamming signal.

On the other hand, the power level of the signal output from the amplification unit is preferably higher than the power level of the signal used in the target, and as a result of experiments, it is necessary to be at least 15dB higher than the reception level of the original signal to effectively block radio waves. confirmed that there is Couplers and circulators are provided at the input and output ends of the array of these amplifiers to function to enable monitoring through a predetermined detection unit. Preferably, the input coupler provided on the input side diverges and routes the signal from the upconversion unit The input detector may function to detect input power, and the output coupler provided on the output side may function to detect the amplified signal by the output detector. In addition, the circulator may be provided at the end side to perform a function of removing additional loss in the RF output path, and the reflected signal detector may detect the reflected signal VSWR. Each of the amplification modules may be connected in parallel to each other to have a predetermined output from the antenna unit 1500 as a selected combination, and the combination and selection of these amplification modules may be performed through an operation in an additional switching unit.
