The radar radiation signal control system of this application has the effects of high signal processing accuracy, strong target recognition capability, and high signal conversion efficiency.

[0032] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0033] like Figure 1 As shown, Figure 1 This is a schematic diagram of a radar radiation signal control system provided in an embodiment of the present invention. The radar radiation signal control system includes an antenna module, a main processing circuit, and a display control circuit. The antenna module is used to receive radio frequency signals and transmit high-power signals. The main processing circuit is connected to the antenna module and includes an automatic parameter measurement module, a frequency conversion module, a high-power amplifier module, and a signal conversion module. The automatic parameter measurement module is connected to the frequency conversion module, which is also connected to the high-power amplifier module and the signal conversion module. The automatic parameter measurement module is used to measure the radio frequency signals received by the antenna module, the frequency conversion module is used to perform frequency conversion processing on the radio frequency signals, the high-power amplifier module is used to amplify the power of the signals, and the signal conversion module is used to perform digital-to-analog conversion or analog-to-digital conversion on the signals. The display control circuit is connected to the main processing circuit and is used to display the signals processed by the main processing circuit. This display control circuit can be implemented through hardware circuitry to complete the human-computer interaction function and control the system's working status.

[0034] Based on the radar radiation signal control system provided in the above embodiments, the antenna module can receive radio frequency signals and transmit high-power signals. The automatic parameter measurement module can accurately measure parameters such as frequency, amplitude, and phase of the radio frequency signals, providing accurate data support for subsequent target detection and positioning. Combined with the processing of the frequency conversion module and the signal conversion module, high-precision signal analysis can be achieved, improving the target detection accuracy and reliability of the radar radiation signal control system. It also achieves efficient conversion between radio frequency signals and other signal forms, improving signal processing speed and efficiency. The high-power amplifier module amplifies the signal, ensuring that the transmitted signal has sufficient energy to propagate to distant targets and obtain a detectable echo, thereby expanding the radar's detection range and coverage, and improving the radar radiation signal control system's detection capability and monitoring range for distant targets. Furthermore, the display control circuit can present the processed signal to the operator in an intuitive way, facilitating target observation, analysis, and decision-making. Through the coordinated work of various modules, the radar radiation signal control system achieves high-precision signal measurement, efficient signal conversion and processing, powerful target detection and positioning capabilities, and enhanced long-range detection capabilities, exhibiting strong signal processing accuracy, strong target recognition capability, and high signal conversion efficiency. It significantly improves the performance and reliability of radar radiation signal control systems, making them suitable for various application scenarios.

[0035] In one embodiment, taking the receiving path as an example, the antenna module can receive radio frequency (RF) signals from the surrounding environment. These signals may include radar signals reflected back from the target. The received RF signals then enter an automatic parameter measurement module, which automatically measures parameters such as the signal's frequency, amplitude, and phase. This parameter information is crucial for subsequent target detection and localization. The measured signal passes through a frequency conversion module, converting the high-frequency RF signal into a lower-frequency intermediate frequency (IF) or baseband signal. Next, the frequency-converted analog signal enters a signal conversion module for analog-to-digital conversion (ADC), converting the analog signal into a digital signal for further processing and analysis. The converted digital signal is then sent to a display control circuit, which can display it on a screen in the form of graphics, images, or numerical values, allowing operators to monitor and analyze target information in real time.

[0036] In one embodiment, taking the transmission path as an example, when transmitting a signal, a baseband signal or intermediate frequency (IF) signal for transmission is first generated. Then, it undergoes digital-to-analog (DAC) conversion via a signal conversion module, converting the digital signal into an analog signal. The converted analog signal enters a frequency conversion module for frequency conversion, transforming the signal from baseband or IF to a suitable radio frequency (RF) for transmission. It is then amplified by a high-power amplifier module to ensure sufficient power to drive the antenna module for effective radiation. Finally, the amplified high-power signal is sent to the antenna module, which converts the signal into electromagnetic waves and radiates them into the air for target detection.

[0037] The radar radiation signal control system of this application embodiment has a high degree of integration. The modules work closely together and coordinate to form an organic whole, which improves the integration and reliability of the radar radiation signal control system, facilitates the installation, debugging and maintenance of the system, reduces the size and weight of the system, and enhances the flexibility of the system.

[0038] In the aforementioned radar radiation signal control system, the antenna module includes a receiving antenna for receiving radio frequency signals within a 360° range and a directional high-gain transmitting antenna for transmitting high-power signals. Isolators are also provided at the output terminals of the receiving antenna and the directional high-gain transmitting antenna.

[0039] like Figure 2 As shown, in this embodiment, the receiving antenna uses a high-performance 2.7GHz to 3.7GHz horn antenna to achieve 1GHz coverage of the S-band. The specific structure of the receiving antenna can be that eight antennas are fixedly installed into a circular array through structural components, thereby enabling the reception of environmental signals within a 360° range.

[0040] The directional high-gain transmitting antenna uses a high-performance 2.7GHz to 3.7GHz horn antenna to achieve S-band coverage of 1GHz, in order to radiate high-power signals.

[0041] It should be noted that in the design of the antenna module, while ensuring the antenna gain and azimuth beamwidth, the elevation beamwidth should be expanded as much as possible to adapt to more complex scenarios.

[0042] Furthermore, given that antenna matching is susceptible to interference from external factors such as load, which can affect VSWR performance, isolators are installed at the outputs of both the receiving antenna and the directional high-gain transmitting antenna to ensure that the antenna module's VSWR performance is achieved. Even under load mismatch, reflected waves can be effectively suppressed, the VSWR can be stabilized, and the antenna can operate stably and efficiently.

[0043] In one embodiment, an SMA socket is used as the output interface for the receiving antenna and the directional high-gain transmitting antenna, which can meet the power tolerance requirements under different conditions (such as a power tolerance requirement of 100W).

[0044] In the aforementioned radar radiation signal control system, the automatic parameter measurement module includes a direction-finding unit and a digital frequency measurement unit. The direction-finding unit is used to compare the amplitudes of the output signals from multiple receiving antennas to perform amplitude comparison and direction finding, while the digital frequency measurement unit is used to measure the frequency of the signal.

[0045] like Figure 3 As shown, in the radar radiation signal control system described above, the direction finding unit includes a limiter, a low-noise amplifier, a filter, a power divider, a DLVA (determiner logarithmic video amplifier) ​​detector, and an ADC circuit.

[0046] In this embodiment, the direction finding unit is used to compare the amplitudes of the output signals of multiple receiving antennas to perform amplitude comparison direction finding. Specifically, the limiter, low noise amplifier, filter, power divider, DLVA detector and ADC circuit are connected in sequence. In addition, the ADC circuit is also connected to the FPGA (i.e., field programmable gate array) circuit.

[0047] In one embodiment, the direction-finding unit can measure the azimuth angle by comparing the output signal amplitudes of eight antennas. Specifically, the radio frequency signal from the antenna module is input to a limiter, which limits the signal amplitude to eliminate fluctuations and keep it within the range that subsequent circuits can process. Then, a low-noise amplifier amplifies the weak signal after limiting, increasing its strength. A filter then removes noise and interference components, retaining the signal within the target frequency range. Next, a power divider splits the pre-processed single signal into multiple paths, preparing for parallel processing by multiple DLVA detectors. The DLVA detectors detect the multiple signals, extracting amplitude, phase, and other characteristic information. Then, an ADC circuit performs analog-to-digital conversion, and the converted signal is processed and analyzed by an FPGA circuit. By comparing the signal amplitudes of multiple antenna channels, the azimuth angle is calculated, and the direction-finding data is output. The direction-finding unit in this embodiment can accurately measure parameters such as the azimuth angle of radar signals, providing precise target position and signal characteristic information for the radar radiation signal control system, thus improving the performance and reliability of the radar radiation signal control system.

[0048] Furthermore, the direction-finding unit is also equipped with a detector and shaping circuit, a 2-to-1 switch, and an 8-to-1 switch. It can acquire radar transmitted pulses. The radar transmitted pulses, after being processed by the detector and shaping circuit, are output to the FPGA circuit. The pulse width is measured using a counting method triggered by the pulse leading edge. Additionally, the 2-to-1 switch can be controlled based on the pulse signal. Then, the RF output is sent to the down-conversion module as the raw signal for data processing in the down-conversion module.

[0049] Furthermore, by setting an eight-to-one switch, multiple control signals are generated based on the signal amplitude received by each antenna, and the output of the signal with the largest signal is selected to ensure that the signal processed subsequently has the best quality and strength.

[0050] like Figure 4 As shown, in the radar radiation signal control system described above, the digital frequency measurement unit includes a splitter, an FFT (Fast Fourier Transform) module, a delay module, a correlator, and an encoding circuit. The splitter is connected to the FFT module and the delay module, respectively. The delay module is also connected to the correlator, and the encoding circuit is connected to the FFT module and the correlator, respectively.

[0051] In this embodiment, the digital frequency measurement unit is used to measure the frequency of the signal. Specifically, the high-speed digital signal output from the frequency converter module is split into eight signals with the same amplitude and phase after entering the splitter. These signals are then processed in parallel by the FFT module, with the eight signals output from the splitter entering the eight channels of the FFT module. The FFT module performs a Fast Fourier Transform on the input signal, converting the time-domain signal into a frequency-domain signal, which is then input to the encoding circuit. Furthermore, the delay module applies different time delays to the signal output from the splitter. The selection of the delay time is based on the principle of phase interferometry, aiming to convert frequency change information into phase change information. The signal output from the delay module then enters the correlator, which compares the phase of the delayed signal with the original signal and outputs the phase difference information, which is then input to the encoding circuit. By combining the FFT module and the delay module for frequency measurement, rapid carrier frequency measurement with high accuracy can be achieved. It can be understood that through the coordinated work of the above components, the digital frequency measurement unit can achieve rapid and accurate measurement of the signal frequency. This design combines the advantages of frequency domain analysis and phase measurement, making it suitable for applications requiring precise frequency measurement.

[0052] like Figure 5 As shown, in the radar radiation signal control system described above, the frequency conversion module includes a down-conversion channel, an up-conversion channel, and a standard frequency circuit, which is connected to the down-conversion channel and the up-conversion channel, respectively.

[0053] In the aforementioned radar radiation signal control system, the downconversion channel includes a coupler, a low-noise amplifier, a programmable attenuator, a filter, a mixer, and an intermediate frequency limiting amplifier.

[0054] In this embodiment, the downconversion channel amplifies the input 2.7–3.7 GHz radio frequency signal and downconverts it to a 1.3–2.3 GHz intermediate frequency signal. Specifically, the input signal is first sampled and its power monitored via a coupler. After amplification by a low-noise amplifier, the signal amplitude is adjusted by a programmable attenuator, and then amplified again by a low-noise amplifier. Next, noise and interference are removed by a filter, completing signal preprocessing. Then, the signal enters the mixer, where the radio frequency signal is mixed with the local oscillator signal, and the spectrum is converted to the intermediate frequency band. The signal is then filtered again to purify it and retain the target frequency band. Finally, the intermediate frequency signal amplitude is stabilized by an intermediate frequency limiting amplifier to ensure a stable output signal for subsequent processing.

[0055] In the aforementioned radar radiation signal control system, the upconversion channel includes an equalizer, a mixer, a filter, a programmable attenuator, and a power amplifier.

[0056] In this embodiment, the upconversion channel upconverts the input 1.8GHz±500MHz intermediate frequency signal to the 3.3GHz±500MHz S-band radio frequency band, and then amplifies the power to output the required radio frequency power signal. Specifically, the input intermediate frequency signal is first amplified and equalized by an equalization amplifier, then enters a mixer, multiplied with the local oscillator signal, and upconverted to the radio frequency band. The mixed signal is then filtered to remove spurious frequencies, resulting in a clean radio frequency signal. Next, it undergoes preliminary power amplification by a first power amplifier, and the power is adjusted by a process-controlled attenuator to ensure that subsequent amplifiers are in their optimal operating state. The signal then undergoes further power amplification by a second amplifier, and finally, the signal is amplified to the required output power level by a third amplifier (e.g., a medium power amplifier), thereby outputting the radio frequency signal.

[0057] In the aforementioned radar radiation signal control system, the standard frequency circuit includes a crystal oscillator, a frequency conversion local oscillator circuit, and a clock circuit.

[0058] In this embodiment, the crystal oscillator can generate a stable reference signal, and the frequency conversion local oscillator circuit can convert the reference signal into the local oscillator signal required by the down-conversion channel and the up-conversion channel. In addition, the clock circuit can obtain the reference signal from the crystal oscillator and output a 2.4GHz clock signal for use by other modules. At the same time, the standard frequency circuit is also equipped with a self-test signal source to generate the radio frequency self-test pulse signal required for self-test.

[0059] like Figure 6 As shown, in the radar radiation signal control system described above, the high-power amplifier module includes a driver amplifier, a high-power amplifier, and a power control and conversion circuit.

[0060] In this embodiment, the high-power amplifier module is used to amplify the S-band radio frequency signal in the range of 2.7 GHz to 3.7 GHz and output an interference signal with the required power level. Specifically, a driver amplifier amplifies a 1W radio frequency input signal and outputs a medium-power signal in the range of 10W to drive the high-power amplifier; the high-power amplifier is implemented using a 100W-level power chip and amplifies the output of the driver amplifier to output the required high-power radio frequency signal.

[0061] In addition, the power control and conversion circuit is connected to the driver amplifier and the high-power amplifier respectively to provide the internal power supply for this module and to take negative voltage protection to ensure the safe operation of the final stage power amplifier, ensuring that the amplifier can operate stably and reliably within its designed parameter range and avoid damage due to abnormal conditions.

[0062] In the aforementioned radar radiation signal control system, the signal conversion module includes an ADC circuit, an FPGA circuit, and a DAC circuit.

[0063] In this embodiment, the FPGA circuit is connected to both the ADC and DAC circuits. Specifically, taking the data acquisition process as an example, the ADC circuit receives the input intermediate frequency signal, samples and quantizes the analog signal, converting it into a digital signal. The FPGA circuit receives the digital signal and performs real-time processing, such as filtering and demodulation. The processed data is output through the FPGA circuit and can be transmitted to other modules or storage devices. Taking the data playback process as an example, the stored playback data is input to the FPGA circuit, which processes the data, performing operations such as modulation and filtering. The processed digital signal is input to the DAC circuit, converting it into an analog signal. The analog signal is output as an intermediate frequency signal for use by subsequent modules. In this embodiment, the signal conversion module achieves analog-to-digital and digital-to-analog conversion of signals through the ADC and DAC circuits, while the FPGA circuit is responsible for the corresponding processing, ensuring accurate conversion and processing of signals between digital and analog forms.

[0064] In the aforementioned radar radiation signal control system, the main control circuit also includes a main control module and a signal generation module. The main control module is used to control the working state of the main control circuit.

[0065] In this embodiment, the main control module can be used to control the working state of the main control circuit, serving as the control and processing core of the radar radiation signal control system.

This application does not impose specific limitations on the embodiments.

[0068] In one embodiment, the signal generation module includes an FPGA chip, a QDR signal storage unit, an ADC signal acquisition unit, a DAC signal playback unit, a clock divider unit, a communication unit, and a GTX interface. The FPGA chip coordinates the operation of each unit, processes signal acquisition and playback data, and controls the signal generation process in real time. The QDR is a high-speed dual-port memory supporting high-speed data read and write. The QDR signal storage unit stores signal data, supporting fast read and write operations by the FPGA chip, ensuring efficient data transmission. The ADC signal acquisition unit acquires analog signals and converts them into digital signals for processing and storage by the FPGA chip. The DAC signal playback unit converts the stored digital signals back into analog signals for output, achieving accurate signal playback. The clock divider unit provides the required clock frequency to each unit, ensuring synchronous operation of the signal generation units. The communication unit is mainly used for data transmission and communication. The GTX is a high-speed serial transceiver interface used for high-speed data transmission, connecting high-speed devices or networks, and improving data transmission efficiency.
