Description

C-band guidance radar simulation system
Technical Field
The invention relates to the technical field of microwaves, in particular to a C-band guided radar simulation system.
Background
Ancient military laws have wonderful discussion of 'deficiency and excess' and 'miraculous and positive', and modern science vow war south and middle alliance weapons are flexibly applied to invisibly and falsely showing. It can be said that the true-false-proof has been an important content for the survival and fight in the war. Under the modern war condition, enemy reconnaissance detection equipment is more sensitive, the identification capability is stronger, the detector information interconnection sharing is higher, the method of only depending on the faithfulness to store the target is undoubtedly passive, the cost is higher, and at the moment, a proper fake target needs to be deployed to confuse the reconnaissance identification of the enemy, interfere the enemy striking decision, weaken the enemy striking effect and improve the survival capability of the important military target of our party. The stronger the false target false indication capability, the higher the true target viability. The simulation performance of the false target is the similarity between the false target and the true target, namely, the false target is consistent with the true target on various exposure technical characteristics (including size, appearance, radiation effect, reflection effect and the like), the better the simulation performance of the false target is, the better the shielding effect on the true target is, namely, the stronger the false display capability is.
In modern high-tech wars, the air defense missile system is an important weapon equipment for air defense on the state of the earth. The guided radar is an important device of an air defense weapon system. Is an important target for attack by both wars and guards.
In order to improve the survivability of the guided radar on a battlefield, inflatable false target false indication is generally adopted to protect a true target. However, the false target can only perform optical false-showing, has no electromagnetic radiation capability, is easy to be discriminated by enemy reconnaissance detection equipment, has poor simulation performance, and gradually reduces the effect of improving the survival capability of the guidance radar under the modern high-tech war condition along with the improvement of the offensive party electromagnetic reconnaissance capability.
The inflatable false target is combined with a guidance radar simulation system, so that the simulation performance of the false target is improved, and the survival capability of the true target can be further improved.
In a general radar simulation system, a high-power transmitter is adopted to output microwave signals, and the microwave signals are radiated to a space through a common fixed low-gain beam antenna.
For example, if the signal strength is required to satisfy the requirements that the receiver with the sensitivity of-65 dBm can receive signals at the 100 km skew distance, the azimuth direction is ± 10 degrees, and the pitch direction is ± 20 degrees, the antenna gain is about 15dB, and the transmitter power needs about 16 kW.
By adopting the scheme, the transmitter has large output power, high cost and large volume, and the antenna beam is fixed in direction. The current guidance radars in America internationally, such as the guidance radar of the patricia weapon system, the guidance radar of the S400 weapon system and the advanced guidance radar in the active work of the army, adopt the phased array radar technology. Because the device can not simulate the function of real guided radar beam fast scanning, the fidelity is poor.
The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.

As shown in fig. 1 to 5, a C-band guidance radar simulation system according to a preferred embodiment of the present invention includes: host computer 1, control machine case 2 and antenna machine case 3. The control cabinet 2 is electrically connected with the upper computer 1, and the control cabinet 2 is used for receiving a control instruction sent by the upper computer 1 and generating a microwave excitation signal according to the control instruction. The antenna case 3 is electrically connected with the control case 2, and the antenna case 3 is used for receiving the microwave excitation signal sent by the control case 2, synthesizing the excitation signal into a 4kW high-power microwave signal through multi-stage amplification and ten paths of space, and radiating the signal to the space.
In one embodiment of the present invention, the interface between the control box 2 and the antenna box 3 is connected by a power supply cable, a communication cable, and a low-loss coaxial cable.
In one embodiment of the present invention, the control box 2 includes a frequency synthesis component 4, a phase shift control component 5, a control circuit board 6 and a power module 7. The frequency synthesis component 4 is configured to generate a corresponding C-band low-power microwave excitation signal according to the received control instruction. The phase-shift control component 5 is configured to receive and process the C-band low-power microwave excitation signal output by the frequency synthesis component 4, generate 10 paths of phase-adjustable microwave excitation signals, and output the signals to the antenna chassis 3. The phase shift control block 5 includes a ten-minute power divider 14, ten phase shifters, ten isolators, ten amplifiers, a wave control plate 12, and a modulator 15.
In one embodiment of the present invention, the antenna enclosure 3 includes a plurality of amplifiers 8, a plurality of isolators 9, a controller 10, and a plurality of horn antennas 11. The plurality of amplifiers 8 are used for receiving 10 paths of phase-adjustable microwave excitation signals generated by the phase-shift control component 5 and performing power synthesis, so as to obtain a microwave signal not less than 4 Kw.
In one embodiment of the present invention, the plurality of amplifiers 8 each employ GaN-based microwave devices and high power combining techniques. The number of the plurality of amplifiers 8 is ten, the number of the plurality of isolators 9 is ten, and the number of the plurality of horn antennas 11 is ten.
In an embodiment of the present invention, the gain of each feedhorn 11 is not less than 11dB, and the antenna gain after the ten feedhorns 11 are spatially power-combined is greater than 21 dB. The gain of each horn antenna 11 at the center frequency is 12.6dB, the azimuth beam width is 24 degrees, and ten horn antennas 11 form a one-dimensional phased array antenna. The ten horn antennas 11 are respectively used for receiving the microwave signals output by the ten amplifiers 8 and radiating the microwave signals to the space.
In practical application, the C-band guided radar simulation system adopts a phased array scheme (namely, a one-dimensional phased array antenna is formed by ten horn antennas 11). The phased array antenna refers to an antenna that changes the pattern shape by controlling the feeding phase of a radiation element (horn antenna 11) in an array antenna. The control phase can change the direction of the maximum value of the antenna pattern so as to achieve the purpose of beam scanning. The cost of the common phased array is high, and the common phased array is difficult to bear for sacrificial equipment such as a false target. The system adopts a wide wave beam in the azimuth direction, one-dimensional phase scanning in the pitching direction, and meets the requirement of covering the airspace by the wave beam in the pitching direction through the phase scanning. The antenna gain is improved to 21dB, and the transmitting power of 4kw can meet the power requirement. With the development of microwave technology, the cost of low-power microwave integrated circuits and chips is greatly reduced, but the cost of high-power microwave circuits, high-power supplies and cooling equipment is not greatly reduced. The simulation system greatly reduces the transmitting power, greatly reduces the cost of the simulation system, and meets the requirements of sacrificial equipment on low cost and high reliability. The beam scanning function of the real radar can be simulated through the rapid beam scanning, and the fidelity is good.
The device of the guidance radar simulation system can be divided into two parts from the hardware composition structure: a control box 2 and an antenna box 3. The control case 2 is responsible for receiving various instructions of manual operation (namely control instructions of the upper computer 1), loading of working parameters of the ground-air missile special radar launching simulation system is completed, and output of low-power signals is completed. The antenna case 3 receives the excitation signal of the control case 2, and the excitation signal is amplified in multiple stages to finally synthesize a 4kW high-power microwave signal which is radiated to the space through the antenna. The interface between the two is realized by a power supply cable, a communication cable and a low-loss coaxial cable.
The control cabinet 2 mainly comprises a frequency synthesis component 4, a phase-shifting control component 5, a control circuit board 6 and a power module 7. The frequency synthesis component 4 generates corresponding C-band low-power microwave excitation signals according to the received command words, outputs 13dBm microwave signals and inputs the microwave signals into a ten-power splitter 14 to respectively drive ten 2W MMIC power amplifiers 8. The phase-shift control component 5 processes the input signal of the frequency synthesizer to generate 10 paths of excitation microwave signals with adjustable phases, and the excitation microwave signals are sent to the antenna cabinet 3. The antenna cabinet 3 includes ten 500W final-stage transmission modules (amplifiers 8), ten isolators 9, and ten horn antennas 11. The ten 500W amplifier 8 modules obtain microwave signals not less than 4Kw through power synthesis. The 500W amplifier 8 module employs GaN-based microwave devices and high power combining techniques. The total output of the amplifier 8 adopts an improved waveguide form, which realizes the transition from microstrip to waveguide and ensures higher power capacity.
The antenna unit adopts a horn antenna 11, and has the advantages of simple structure, easy processing, large power capacity and convenient adjustment and use. The reasonable selection of the size of the horn can obtain good radiation characteristics, relatively good main lobe, relatively small side lobe and relatively high gain. In order to meet the requirement of 21dB of antenna transmission line gain, the gain of a single radiation unit (the horn antenna 11) is not less than 11dB, ten horn antennas 11 are subjected to space power synthesis, and the final antenna gain reaches the requirement of 21 dB. The antenna has novel design concept, adopts the fan-shaped horn as the radiation unit, and places the horn in a crossed and staggered way for reducing the distance between the radiation units (horns), and the measured data shows that the performance of the antenna reaches the preset design index. The horn antenna 11 has a gain of 12.6dB in a radiation unit at a central frequency, a beam width of 24 degrees in an azimuth direction, and a scanning range +/-20 degrees in a pitch direction through phase scanning.
