[0033] refer to Figure 2This application can realize the limiting processing, low-noise amplification, and re-conversion of the signals of each frequency band received by the antenna to the intermediate frequency, and send the low-frequency signal generated by the signal processing module to the antenna module after up-conversion, amplification, and filtering. Among them, the signals in the range of 30MHz to 475MHz are directly sampled without frequency conversion, and the DDS+PLL system is used for frequency conversion in the range of 475MHz to 18GHz. When the broadband signal is transmitted, the PLL accurately cuts the local oscillator frequency, and the DDS technology realizes demodulation and frequency conversion; in addition, the receiving channel and the transmitting channel have attenuation control function. At the same time, the local oscillator signal generation module of the module generates a 30MHz to 18GHz radio frequency signal according to the input signal.
[0034] On the basis of the above embodiments, the present application also provides an electronic countermeasure load, the electronic countermeasure load 30 includes a first antenna 17 to a fourth antenna 20, a microwave transceiver module 10 as provided in any of the above embodiments, an instantaneous frequency measurement receiver module, a signal processing module, a Beidou timing module and a secondary power supply module; the first antenna 17 to the fourth antenna 20 are communicatively connected to the microwave transceiver module 10; the microwave transceiver module 10 is communicatively connected to the instantaneous frequency measurement receiver module 12 and the signal processing module 11 respectively; the instantaneous frequency measurement receiver module 12 is communicatively connected to the signal processing module 11; wherein, the first antenna 17 to the fourth antenna 20 are communicatively connected to the microwave transceiver module 10; The four antennas are used to receive reconnaissance signals and send the reconnaissance signals to the instantaneous frequency measurement receiver module 12 and the signal processing module 11; the instantaneous frequency measurement receiver module 12 is used to receive the reconnaissance signal, process the reconnaissance signal, obtain reconnaissance signal parameter information, and send the reconnaissance signal parameter information to the signal processing module 11; the signal processing module 11 is used to receive the reconnaissance signal parameter information and the reconnaissance signal, process the reconnaissance signal parameter information and the reconnaissance signal to obtain reconnaissance target information, and obtain interference information based on the reconnaissance target information, and send the interference information to the microwave transceiver module 10.
[0035] The first antenna 17 to the fourth antenna 20 include a whip antenna of 30 MHz to 460 MHz, a whip antenna of 460 MHz to 2 GHz, and two planar spiral antennas of 2 GHz to 18 GHz.
[0036] Signal processing module 11 primarily consists of two ADC chips, one DAC chip, one high-performance FPGA, one DSP, and other auxiliary circuits. It performs A / D conversion and signal sampling on the intermediate frequency (IF) signal transmitted from the microwave module. It stores the signal in the digital domain and generates an interference signal through multi-dimensional "time-frequency-energy" modulation. A D / A converter then converts the digital interference signal into an IF signal, which is then transmitted to microwave transceiver module 10. Furthermore, signal processing module 11 is responsible for information processing control, communication modules, information processing, data processing, and cross-link control with other payloads.
[0037] refer to Figure 3 After receiving the signal, antennas 17 through 20 transmit it to the microwave module for amplitude limiting, low-noise amplification, and conversion to an intermediate frequency (IF) before sending it to signal processing module 11. Simultaneously, a radio frequency signal is transmitted from microwave transceiver module 10 to instantaneous frequency measurement receiver module 12, thereby obtaining a rough estimate of the radiation source's frequency and bandwidth. This IF measurement receiver module 12 then transmits this frequency measurement information to the signal processing module. Signal processing module 11 receives the IF signal from microwave transceiver module 10 and processes it in conjunction with the information from IF measurement receiver module 12, completing the electronic reconnaissance mission. Simultaneously, signal processing module 11 generates corresponding jamming signals for different target types through multi-dimensional "time-frequency-energy" modulation. These signals are then transmitted to microwave transceiver module 10, processed by microwave transceiver 10, and sent to the antennas, completing the electronic jamming mission.
[0038] In an embodiment of the present application, the electronic countermeasure load 30 also includes a Beidou timing module 13 and a secondary power supply module 14, wherein the Beidou timing module 13 is communicatively connected to the signal processing module 11, and the Beidou timing module 13 is used to generate a timing signal; the secondary power supply module 14 is communicatively connected to the signal processing module 11, and the secondary power supply module 14 is used to supply power to the Beidou timing module 13, the microwave transceiver module 10, the instantaneous frequency measurement receiver module 12 and the signal processing module 11.
[0039] The secondary power supply module 14 mainly includes a filter circuit, a DC-DC conversion module and related structural components to complete the power supply task of each module.
[0040] The Beidou timing module 13 consists of time and frequency components, precise clock synchronization software and corresponding structural parts. It can receive BDS / GPS time source signals, obtain time, position and other information, and generate high-precision 1pps, TOD, 100MHz time and frequency signals. It has high-precision timing function when satellite signals cannot be received.
[0041] like Figure 4 As shown, the payload reconnaissance mission workflow of the present invention is as follows:
[0042] After receiving the external signal, the payload antenna sends it to the microwave transceiver module. At this time, the 30MHz~475MHz signal adopts direct sampling without frequency conversion and is transmitted from the microwave transceiver module to the signal processing module through SMP; the 475MHz~18GHz signal adopts the DDS+PLL frequency conversion system. The signal is transmitted from the microwave transceiver module to the instantaneous frequency measurement module through one SMP. After receiving the signal, the instantaneous frequency measurement module measures the center frequency and transmits the frequency measurement information to the signal processing module. Then the signal processing module generates the local oscillator control signal based on the frequency measurement information. The signal is then transmitted to the microwave transceiver module. For narrowband signals, primarily fire control radar and communication signals, the microwave transceiver module receives the local oscillator (LO) control signal and uses a phase-locked loop (PLL) to switch to the appropriate LO (88 200MHz bands). The RF signal is filtered and frequency-converted to a 360MHz intermediate frequency (IF) and amplified before being transmitted to the signal processing module for further processing. For wideband SAR signals, the PLL switches to the appropriate LO for frequency conversion while simultaneously demodulating the signal using a dynamic distributed multi-signal (DDS) to bring it close to a 360MHz zero IF (0-10MHz) before transmission to the signal processing module. The IF signal enters the signal processing module via the SMP, is sampled by the ADC, and then fed into the FPGA, where digital channelization, channel detection, and pulse parameter measurement are performed. The measurement data is then transmitted to the DSP via the SRIO interface between the FPGA and DSP for subsequent information processing, including DOA measurement, pulse sorting, emitter identification, emitter direction finding, emitter location, and threat level assessment. The DSP transmits measurement reports via the external SRIO interface and simultaneously receives control information from the host computer.
[0043] like Figure 5 As shown in the figure, the work process in the payload interference task is as follows:
[0044] After the payload detects a target signal, the intermediate frequency (IF) signal, filtered, mixed, and amplified by the microwave module, is converted to a digital signal through AD sampling in the signal processing module and stored in its memory. Jamming decisions are then made for each target, employing targeted countermeasures such as partial pulses and coherent noise. The host computer issues a jamming command, which reads the digital signal from the signal processing module's memory. This signal undergoes a multi-dimensional "time-frequency-energy" modulation in the digital domain to generate a digital countermeasure jamming signal. A D / A converter then converts the digital jamming signal to a 360MHz IF signal (from 475MHz to 18GHz, directly sampled from 30MHz to 475MHz), which is then transmitted to the microwave module along with local oscillator (LO) control information. The microwave module receives the IF input and LO control information from the signal processing module, switches to the appropriate LO using a PLL (Program Locked Loop), converts the IF input signal to the appropriate frequency band, amplifies it, and transmits it to the corresponding antenna for radiated radiation toward the target, completing the jamming mission.
