Description

Jammer for drones having a fire detachment structure {JAMMER FOR ANTI-DRONE HAVING FIREARM MOUNTING AND DISMOUNTING STRUCTURE}

The present invention relates to technology for preventing the flight and infiltration of drones, and more specifically, to a jammer for drones that is portable and mobile and capable of jamming unmanned aerial vehicles such as drones that infiltrate through the air. .

Recently, with the development of drone technology, various types of drones have been developed and supplied to the public. International companies 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. These drones can be seen as a type of unmanned aerial vehicle, which is smaller and lighter than military unmanned aerial vehicles, which means that detection is relatively difficult. With the spread of these drones, low-cost unmanned aerial vehicles (UAVs) are becoming a potential threat to commercial aviation facilities, essential infrastructure, confidential facilities, and even the military. In other words, depending on the combination of drones with photo or video recording equipment, there is always a possibility of misuse, and therefore, there is a possibility that it may pose a threat to various security facilities or social infrastructure. In fact, in Washington, there was a case in which a hobbyist drone crashed inside the White House and a security alert was issued, and in France, in preparation for an incident where drones appeared at a nuclear power plant, the police and air force could shoot down a bird-sized drone. There are also cases where a request was made to develop an existing weapon. Additionally, in Korea, the need for so-called anti-drone defense facilities that can prevent aircraft from intruding into no-fly zones is emerging following an incident in which a North Korean drone crashed while filming the Blue House and downtown Seoul.

However, both domestically and internationally, the development of equipment that can effectively respond to intrusions by unmanned aerial vehicles such as drones that operate by receiving frequencies in the air is still quite minimal.

Meanwhile, wireless communication networks used in drones transmit radio waves into the air to enable exchange of information in various forms such as one-to-one, many-to-one, and one-to-many. These wireless communication networks are used to disrupt receivers that receive information. This is called wireless communication jamming.

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

Looking at this, the oscillation signal from the oscillator 10 is transmitted to the upconverter 40 through the buffer 30. The upconverter 40 multiplies the frequency of this oscillation signal and up-converts it to the frequency band of the wireless communication device to be interfered with. In order to prevent the upconverter 40 from free running when power is applied to the device, the power-on reset unit 20 turns on the upconverter 40 after a certain period of time has passed after power is applied. It serves to reset.

However, the radio jammer of this prior art operates in a predetermined fixed frequency band, is fixed for inputting control power, and has a fixed antenna, so not only is the equipment bulky and mobility is significantly reduced, but it also operates in various bands. Because it is difficult to respond to the frequency, it is difficult to apply it to unmanned aerial vehicles such as drones that can penetrate the air.

The present invention was developed to overcome the problems of the prior art described above, and has a firearm detachable structure that can respond to various RF bands and respond flexibly according to the situation as well as aerial penetration of unmanned aerial vehicles, while providing excellent portability and maintainability. The purpose is to provide a jammer for drones.

The present invention to solve the above problem includes an antenna unit (2000) that has a casing (2500) for accommodating one or more antennas therein and is detachable through a bracket unit (2100) on a rail disposed on the barrel of a firearm. ), a controller unit 1000 that is connected to the antenna unit through a control line and generates a frequency and transmits it to the antenna unit, and a battery unit 1600 that transmits power to the controller unit. A jammer for a drone having a fire detachable structure. provides.

The bracket portion includes a lower slot 2130 into which the mounting protrusion protruding from the upper side of the casing is inserted in the front-back direction, an upper slot 2140 formed on the upper side of the lower slot and into which the rail portion is inserted in the front-back direction, and the lower slot. It is desirable to have a base portion 2110 extending to both sides.

Specifically, when the anteroposterior position of the mounting protrusion inserted into the lower slot of the bracket unit is determined, the adjustment means is inserted downward into the adjustment hole formed in the base portion to fix the position with respect to the casing, and the rail portion inserted into the upper slot is fixed. Once the front-to-back direction position is determined, the positioning means is inserted laterally into the positioning hole formed by penetrating the upper slot to the left and right, thereby fixing the position of the barrel, so that the casing is firmly supported facing the surface and the barrel is vibrated. It is possible to optimize the rail configuration while minimizing heat transfer.

The bracket part allows the antenna part to be selected and fixed in an anteroposterior position with respect to the gun barrel, and vibration and heat transfer caused by firing a bullet can be reduced by separating the antenna part from the gun barrel.

Additionally, the antenna unit may be provided with a handle unit 2510 that is disposed on the rear side of the casing and held.

Meanwhile, it may further include a wearable part 3000 that has a front pocket that accommodates the controller part and the battery part and can be worn on the body.

According to the above-described configuration of the present invention, the antenna unit is separated from the battery unit and the controller unit and connected and used only when necessary in the operating environment, thereby increasing portability and maintaining excellent maintenance ability.

In addition, only the configuration for transmitting radio waves is configured to be detachable from the barrel, so that the firing direction of the bullet and the radiation direction of radio waves can be matched without interfering with the original purpose of use as a firearm, allowing accurate aiming and firing. , because the volume and weight of equipment that must be supported with the arm can be reduced, portability as well as aiming ability can be dramatically improved.

In addition, since it can be easily attached and detached from the lower side of the barrel of the firearm by a bracket, it is convenient to set a precise position, which has the effect of optimizing the distribution of load and the gripping position by overcoming individual differences of the operator.

Hereinafter, a jammer for a drone having a firearm detachment structure of a preferred embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

However, the embodiments described below are merely intended to provide a detailed description so that a person skilled in the art can easily implement the invention, and this does not limit 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. Additionally, when a part is said to 'include' a certain component, this does not mean that other components are excluded, but that it can further include other components, unless specifically stated to the contrary.

The present invention basically provides a jammer including an antenna portion that is detachable from the barrel of a portable firearm through a bracket portion.

The portable firearm described in the present invention refers to a weapon that can be carried and shoots bullets, etc. In the description of the present invention regarding such portable firearms, the form of a rifle is used as a main example, but it should be understood that the firearm includes various types of weapons that can be held and/or shoulder-mounted and have a predetermined aiming structure.

Figure 2 is a side view for explaining a jammer for a drone having a firearm detachment structure of the present invention.

In the illustrated embodiment, an antenna unit 2000 capable of radiating a predetermined jamming frequency is mounted on a portable firearm 2010, and a controller unit and/or battery that generates and transmits a jamming signal to the antenna unit 2000. Wealth can be connected to this. Configurations related to the generation and transmission of the signal will be described later.

A rifle as a portable firearm (2010) is equipped with a stock that can be mounted on the shoulder, a percussion handle, a grip handle, an aiming rail, and a barrel.

It can be considered that the antenna unit 2000 for frequency radiation itself is configured in the same shape as a gun, but in this case, it is difficult to adapt to various environments because it must be used only for jamming purposes. In particular, in emergency situations, when neutralization through frequency is not possible, immediate neutralization through physical triggering may be necessary, and it is necessary to arrange it so as not to impede its use as a firearm.

In the present invention, in order to solve this technical problem, the antenna unit (2000) is configured to be detachable from a ready-made portable firearm (2010).

At this time, since the firing of bullets, etc. and the emission of frequencies are aimed at a remote target, it is better to have the same direction. Accordingly, it would be preferable that the orientation direction of the antenna unit 2000 be arranged parallel to the gun barrel.

When placing the antenna unit 2000 on the side of the gun barrel, you can choose to place it on the upper side or on the lower side. If placed on the upper side, it may be difficult to aim and fire because it blocks the sight of the aiming rail. To solve this problem, a complex structure must be adopted. Additionally, if placed laterally, there is a possibility of eccentricity of the weight.

However, when the antenna unit 2000 is placed on the barrel side, there may be problems in aiming and maintaining the state due to the increase in weight at the front, and there is also a possibility that directionality may be disturbed when operating the radiation trigger.

In the present invention, in order to solve this problem, the antenna unit 2000 is placed on the lower side of the barrel as the most preferred embodiment. The antenna unit 2000 is provided with a handle unit 2510 so that it can be gripped by hand. Accordingly, balanced support is possible by the user holding the handle portion 2510 from the front with one hand and the handle for holding the portable firearm 2010 with the other hand from the rear. In addition, the antenna unit 2000 adopts a structure that allows the user to select the optimal position, more precisely, the position in the forward and backward directions with respect to the gun barrel. Embodiments related to this will be described later.

This antenna unit 2000 has a casing 2500 that accommodates one or more antennas therein, and a mounting space (reference number not shown) where the handle unit 2510 and the trigger unit 2020 are placed at the rear of the casing 2500. This is composed.

The trigger unit 2020 may function as a switch that starts emitting the frequency transmitted from the controller unit 1000.

Taking the type of portable firearm (2010) shown as an example, with the antenna unit (2000) removed, the operator holds the stock on the shoulder, holds the percussion handle with the dominant hand, and places the other hand on the barrel to aim and shoot. Do it.

In the present invention, since the antenna portion 2000 is disposed on the barrel and constitutes the handle portion 2510, the handle portion 2510 can be held instead of the barrel, and the firearm can be further supported even when used for the specific purpose of firing bullets. easy. The handle portion 2510 is configured at the rear end of the casing 2500 and may be placed immediately in front of the magazine.

Meanwhile, it can be considered that the antenna unit 2000 is formed integrally with the casing 2500 and the battery unit that supplies power with a controller for modulating, synthesizing, and generating a predetermined frequency. However, in this case, excessive weight may be added to the portable firearm (2010), impeding portability and causing difficulty in aiming.

Accordingly, one or more terminal units 2322 may be provided to enable connection of the controller and/or battery unit to the antenna unit 2000 only when in use. Considering the coupling relationship disposed at the bottom of the gun barrel as described above, it is easier to operate the terminal portion 2322 if it is located on the lower side of the casing 2500.

Additionally, the bracket portion 2100 is configured to provide coupling force between the antenna portion 2000 and the barrel portion. The bracket portion 2100 is coupled to the rail portion 2011 formed or coupled to the gun barrel on the upper side and the upper portion of the antenna portion 2000 on the lower side.

In the case of recent rifles, for example, K2C, a domestically produced service rifle, a Picatinny rail, which is an international standard, is configured on the lower side, and the bracket part 2100 can have a structure that can be coupled to the rail part 2011. there is. Specific examples of this will be described later.

To prevent damage to the antenna unit 2000 due to heat generated from the gun barrel, the bracket unit 2100 can perform the function of separating the gun barrel and the antenna unit 2000.

The antenna unit 2000 may be provided with one or more antennas capable of radiating radio waves for a predetermined band, and preferably, two antennas may be accommodated in the casing 2500 to cover each frequency band. You can. Since each antenna performs the function of blocking the radio control frequency and/or tracking operation frequency and/or video transmission frequency of the drone operating in the air, it has excellent directivity and has a beam width of 20 degrees to minimize the impact on other locations. It will be able to effectively transmit jamming waves by targeting a blocking object at a distance.

Figure 3 is a diagram for explaining an embodiment of the bracket part in the drone jammer having the firearm detachment structure of the present invention.

A mounting protrusion 2520 is disposed on the upper side of the casing 2500 of the antenna unit 2000, preferably on the upper surface of the casing 2500 adjacent to the handle unit 2510.

The mounting protrusion 2520 may be fastened to the upper surface of the casing 2500 by bolting, and for this purpose, one or more mounting holes 2521 may be disposed through the mounting protrusion 2520.

The mounting protrusion 2520 may have a shape that roughly corresponds to the rail portion 2011 of the portable firearm 2010, and may include a plurality of protrusions arranged in the longitudinal direction as shown.

The mounting protrusion 2520 has a predetermined step where the bracket portion 2100 can be caught when viewed from the front, and has a vertex protruding from the upper side of the step to the side, so that the mounting protrusion 2520 has an overall approximately hexagonal shape. However, it is not limited to the above shape.

It may be considered that the mounting protrusion 2520 of the antenna unit 2000 is directly fastened to the barrel of the portable firearm 2010, but in that case, durability and operational reliability may be deteriorated due to heat or impact. . Accordingly, the bracket unit 2100 performs the function of separating the antenna unit 2000 and the gun barrel from each other, thereby preventing problems caused by heat and vibration in advance.

As described above, the bracket portion 2100 performs the function of connecting the barrel portion and the antenna portion 2000. Specifically, the bracket portion 2100 functions to vertically connect the rail portion 2011 on the barrel side and the mounting protrusion 2520 of the antenna portion 2000.

In the illustrated state, the rail part 2011 is shown separated from the barrel for convenience of explanation.

In order to mainly support the load upward and downward, the bracket portion 2100 may be coupled to the rail portion 2011 and the mounting protrusion 2520 in a sliding manner in the forward and backward directions. Accordingly, the bracket part 2100 may be composed of a lower part that is coupled to the mounting protrusion 2520 and fixes the position, and an upper part that is coupled to the rail part 2011 and fixes the position.

Specifically, the lower portion of the bracket portion 2100 includes a lower slot 2130 into which the mounting protrusion 2520 can be inserted in the longitudinal direction, and the upper portion includes a lower slot 2130 into which the rail portion 2011 can be inserted longitudinally. Includes an upper slot (2140). The lower slot 2130 and the upper slot 2140 are formed in the fastening part 2150 that protrudes upward from the base part 2110, and a partition 2152 may be formed to separate them.

A base portion 2110 is formed in the lower part of the bracket portion 2100 to be wider in the left and right directions than the fastening portion 2150, and the base portion 2110 has an overall plate shape. The lower part and the upper part may have different positioning methods, and the lower part may include an adjustment hole 2111 penetrating in the up and down direction from the base part 2110.

An adjustment means (not shown), such as a bolt, is inserted into the adjustment hole 2111, and the separation distance between the bottom of the base portion 2110 and the top of the casing 2500 is adjusted according to the inserted length of the adjustment means. That is, after the mounting protrusion 2520 is inserted into the lower slot 2130 in the front-back direction and the position is determined, the adjustment means is inserted into the adjustment hole 2111 of the base portion 2110, and the end of the adjustment means is connected to the casing 2500. When the base portion 2110 is separated from the upper surface of the casing 2500 by contacting the upper surface of the casing 2500, the surfaces of the mounting protrusion 2520 and the lower slot 2130 come into close contact and the position is fixed by friction.

It may also be considered to adopt a structure similar to the lower part for the upper part. However, there are concerns about the morphological complexity of the barrel area and excessive vibration and heat transfer, and taking this into consideration, it is desirable to apply a structure for direct positioning on the rail portion (2011).

According to this concept, the upper portion may be formed with a positioning hole 2151 penetrating the side of the upper slot 2140 in the fastening portion 2150. The positioning hole 2151 is formed to penetrate the left and right sides of the fastening part 2150, and a positioning means (not shown) such as a bolt or a pin is inserted into the positioning hole 2151, and the beam exposed in the upper slot 2140 is positioned as a laser beam. It hangs on some (2011) uneven parts and determines the position in the front and back directions. When the rail portion 2011 and the bracket portion 2100 are coupled in this way by pin coupling, it has the advantage of being able to cushion vibrations in the vertical and forward directions to some extent compared to the portion coupled to the casing 2500.

By the configuration of the fastening part 2150, the adjustment hole 2111, and the positioning hole 2151 as described above, the position of the antenna part 2000 and the bracket part 2100 from the portable firearm 2010 can be adjusted in the forward and backward directions. It can be freely varied.

Figure 4 is a diagram showing a state in which the drone jammer having the firearm detachment structure of the present invention is worn on the body.

When it is necessary to respond to a drone while the portable firearm (2010) is being carried, the rail portion (2011) and the antenna portion (2000) disposed on the barrel of the portable firearm (2010) are positioned so that the bracket portion (2100) moves in the forward and backward directions. They are combined and connected in a sliding manner, and when predetermined positioning and fixation are achieved, the combination of the portable firearm (2010) and the antenna unit (2000) is completed. Considering the arrangement of the adjustment hole 2111 and the positioning hole 2151 of the present invention, it would be preferable to combine the bracket portion 2100 and the mounting protrusion 2520 first.

The portable firearm 2010 may be carried and used while connected to the antenna unit 2000, or it may be carried with the antenna unit 2000 separated and then combined and used in a place where jamming is required.

After the portable firearm 2010 and the antenna unit 2000 are combined in this way, the separately configured controller unit 1000 and battery unit 1600 are connected through a predetermined line. One end of the control line 1010 is coupled to the terminal portion 2322 disposed at the bottom of the antenna portion 2000, and the other end is coupled to a predetermined terminal configured in the controller portion 1000.

The controller unit 1000 and the battery unit 1600 may be configured as one body, but considering portability and maintainability, it is preferable that they be configured separately as shown. The battery unit 1600 and the controller unit 1000 are connected to each other through a power line 1020, and power for frequency generation and oscillation is supplied.

The controller unit 1000 and the battery unit 1600 can be carried in a form worn on the body, and for this purpose, they can be attached to and detached from the wearing unit 3000 provided with a predetermined pocket.

As shown, the wearing unit 3000 is configured in the form of a vest, and a pocket for mounting the controller unit 1000 is placed at the front, making it easy to operate to set the frequency range and radio wave intensity.

As described above, if the antenna unit 2000, the controller unit 1000, and the battery unit 1600 are configured to be separate from each other and connected as needed, portability is improved and parts requiring repair can be immediately replaced or repaired. It can be easily done on site. In particular, when combined with a firearm, excessive increase in volume and weight can cause problems in aiming and firing in the field, as mentioned above, and since only the antenna unit (2000) is directly mounted on the portable firearm (2010) and used, the firearm is unique. It should be noted that aiming and radiation can be achieved smoothly even when used as a jammer without hindering the purpose.

Figure 5 is a block diagram for explaining the configuration of the controller unit in the drone jammer having the firearm detachment structure of the present invention.

As described above, the antenna unit 2000 performs the function of radiating a frequency for disturbing or controlling a drone. If the concept of the present invention is applied, the frequency band subject to disturbance can be set in various ways, of course. am.

If classified by the function of the frequency transmitted from the antenna unit (2000), it can be classified into radio control frequency, tracking (GPS) frequency, and video transmission frequency.

When transmitting a jamming signal to neutralize a drone, for example, the Frequency Hopping method or the Spread Spectrum method can be applied to neutralize the remote control transmitting and receiving module.

At this time, the frequency band that can be applied to neutralize the unmanned aerial vehicle in the air is optional, but is preferably GPS (1,160 MHz ~ 1,790 MHz), ISM 2.4 GHz band (2,400 MHz ~ 2,483.5 MHz), and ISM 5 GHz band (5,725 MHz) ~ 5,825 MHz), and it is desirable to apply a broadband high-gain antenna in the 1,570 MHz to 2.5 GHz band.

Here, the GPS band is the A-band (1560~1605MHz) including GPS L1 (1575.42MHz), GLONASS L1 (1601.156MHz), and BeiDou B1 (1561.098MHz) bands, GPS L2 (1227.6MHz), and GPS L5 (1786.45MHz). MHz), it can be viewed as the B band (1160~1280MHz), which includes GLONASS L2 (1245.34MHz), GLONASS L3 (1201.7MHz), BeiDou B2 (1207.14MHz), and BeiDou B3 (1268.62MHz) bands.

More preferably, a case where a dual-polarization antenna that simultaneously transmits vertical and horizontal polarization waves can be considered as the broadband high-gain antenna. In addition, it would be desirable for the gain and structure to be over 10dBi and for the 3dB beam width of the antenna to be limited to within 20 degrees considering the accuracy of radiation into the air and remote radio wave transmission.

In the present invention, the configurations that can be connected to the antenna unit and configured to be accommodated in the controller unit 1000 to transmit a radio signal with a predetermined intensity are as follows.

The controller unit 1000 may include a signal generation unit 1100, an upconversion unit 1200, an amplification unit 1300, a filter unit 1400, and a management unit 1700. As described above, the battery unit 1600 can be connected to the power line 1020. In some cases, the battery unit 1600 may function as a power supply unit and receive external power 1610.

The signal generator 1100 can generate a radio wave blocking signal and, as will be described later, can perform a function of sweeping two or more signals in the IF (Intermediate Frequency) band. The frequency band can be selected by the user and input through the management unit 1700.

At this time, as described above, one or more DDS (Direct Digital Synthesizer) and/or FPGA (Field Programmable Gate Array) may be selected and combined to generate two or more signals. The signal generator 1100 can generate a jamming signal using white noise. As will be described later, it may be composed of individual signal generators to generate signals independent of each other for each channel, and in some cases, the number of channels may be increased. It may be composed of an individual signal generator corresponding to . As mentioned above, it is preferable that the band applied here is the GPS and/or ISM 2.4 GHz band and/or the ISM 5 GHz band.

The upconversion unit 1200 upconverts the signal in the IF band generated by the signal generation unit 1100 to the RF band, which is a guard frequency band. This upconversion unit 1200 functions to upconvert the IF frequency generated by the signal generation unit 1100 to a commercial frequency band.

The upconversion unit 1200 converts the carrier signal of each channel generated by the signal generation unit 1100 into a predetermined RF frequency band.

The amplification unit 1300 amplifies the signal output from the upconversion unit 1200. The power level of the signal output from the amplification unit 1300 may have a higher power level than the power level of the signal in the band subject to disturbance.

In the present invention, power management is performed for portability, but since it is necessary to adapt according to aiming and distance for unmanned aerial vehicles such as moving drones, the amplifier 1300 includes a plurality of amplification modules to satisfy such complex requirements. It can be operated by combining.

The filter unit 1400 suppresses unwanted wave signals in an unwanted band among the signals output from the amplification unit 300, selects only signals within the designated band, combines them as a jamming signal, and sends them to the antenna unit 1500. Functions to output. This filter unit 1400 can function to reduce the influence of interference on adjacent frequencies due to the output frequency of the amplification unit 1300.

When a frequency band for which disturbance is desired is selected, the management unit 1700 can select an input corresponding to the selection. However, in the present invention, when neutralizing an unmanned aerial vehicle, the management unit 1700 can preset the frequency bands of GPS and ISM as the Input Frequency Range, combine them in a wide band, and transmit them to the antenna as a single output. .

Figure 6 is a block diagram for explaining an embodiment of the amplification unit in the drone jammer having the firearm detachment structure of the present invention.

According to one embodiment, the jammer for a drone having a fire detachment structure of the present invention has an amplifier 1300 and a plurality of amplification modules 300a, 300b,... connected in parallel to control the output according to the distance. It can be configured.

Looking at each amplification module 300a, it will be comprised of a driving amplifier 1320 that amplifies the input signal input from the upconversion unit 1200, and a main amplifier 1330 that removes and amplifies the distortion signal. This amplifier can be configured by combining various known amplifying elements.

The input and output terminals of the array of these amplifiers may be equipped with couplers and circulators to enable monitoring through a predetermined detection unit. Preferably, the input side coupler 1310 provided on the input side detects the energy from the up-conversion unit 1200. It can function to branch and route the signal and detect the input power in the input detection unit 1311, and the output side coupler 1340 provided on the output side can function to detect the amplified signal in the output detection unit 1341. You can. In addition, the circulator 1350 is provided at the end and can perform the function of removing additional loss in the RF output path, and can detect the reflected signal (VSWR) in the reflected signal detection unit 1351.

Note that, depending on the configuration of these detection units (1311, 1341, and 1351), it is possible to overcome the limitations of being a compact portable device and implement a protection function for the device due to over-output.

Each amplification module (300a...) can be connected in parallel to each other to have a predetermined output from the antenna unit 1500 as a selected combination. For example, each amplification module (300a) can be set to 20W. You can. At this time, it can have 20W and 45% efficiency in the first band (1,160~1,790MHz), which is the above-mentioned frequency band, 20W and 45% efficiency in the second band (2,400~2,483.5MHz), and the third band (2,400~2,483.5MHz). It can have 20W and 35% efficiency at 5,725~5,825MHz). However, the above output is an example and is not necessarily limited to the described example.

Combination and selection of these amplification modules can be accomplished through predetermined switching.

In an embodiment of the present invention, amplification modules are configured to be accumulated in parallel, and the number of such arrangements is optional. In the case of conventional amplifiers, the output is limited because interference amplification occurs within adjacent frequencies. However, when connected and combined in parallel as in the present invention, a practical amplification function can be guaranteed and a signal interference prevention function can be achieved at the same time. It should be noted that this is.

Figure 7 is a block diagram showing a signal generation unit in a jammer for a drone having a fire detachment structure of the present invention, and Figure 8 is a block diagram showing an upconversion unit.

The signal generator 1100 can be understood as a digital signal generator that generates a radio wave blocking signal, and includes a CPU (1110), FPGA (1120), and DDS (1130) that function by receiving control power from the power supply unit 1600. It may be configured to include. In this regard, various known configurations may be applied, so detailed description will be omitted.

At this time, in the signal generator 1100, the sweep speed adjustment function (adjustable from 6.67ns to 1us), sweep step adjustment function (5KHz to 1MHz), bandwidth setting function, and FPGA alarm ( Alarm function, FPGA reset function, etc. can be provided.

The upconversion unit 1200 functions to convert the IF signal generated by the signal generation unit 1100 into a radio wave cutoff frequency, and for this purpose, it may be configured with a plurality of BPFs, an IF mixer, and an RF mixer.
