[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] Figure 1 A flowchart of a receiver detection method provided by an embodiment of the present invention.

[0023] like Figure 1 As shown, a receiver detection method comprises the following steps:

[0024] Importing real-time radar data, multiple historical radar data, and multiple radar environment parameters, and building a performance test model through all the historical radar data and all the radar environment parameters;

[0025] The real-time radar data is tested by the performance test model to obtain a target dynamic scene digital signal;

[0026] The target dynamic scene digital signal is input into the receiver to be detected for detection and analysis, and the analysis result is used as the detection result of the receiver to be detected.

[0027] In the above embodiment, a performance test model is constructed through historical radar data and radar environmental parameters, and the target dynamic scene digital signal is obtained by testing the real-time radar data through the performance test model. The target dynamic scene digital signal is input into the receiver to be detected for detection and analysis, and the analysis result is used as the detection result of the receiver to be detected. It is not limited by the number of traditional special system signal sources, and the problem of the receiver can be discovered as soon as possible during the module-level debugging stage and the algorithm design can be optimized. The problems of concentrated debugging workload, uncontrollable detection progress and slow technology iteration are solved. The receiver performance can be tested around the clock and in all regions, which speeds up the iteration speed of technology, reduces the detection cost, and has good application value.

[0028] Optionally, as an embodiment of the present invention, the radar environment parameters include application scenario parameters, target objects and interference noise.

[0029] The process of constructing a performance test model using all the historical radar data and all the radar environment parameters includes:

[0030] A performance test model is constructed using all of the historical radar data, all of the application scenario parameters, all of the target objects, and all of the interference noise.

[0031] It should be understood that according to the special signal pattern of the test target, a digital model (i.e., performance test model) of the radar radiation source signal (i.e., historical radar data), application scenario (i.e., application scenario parameters), target object and interference noise is constructed in the special signal waveform design software.

[0032] In the above embodiment, a performance test model is constructed by using all historical radar data and all radar environmental parameters, which solves the problems of concentrated debugging workload, uncontrollable detection progress and slow technology iteration. The receiver performance can be tested around the clock and in all regions, which speeds up the iteration of technology, reduces the detection cost and has great application value.

[0033] Optionally, as an embodiment of the present invention, the process of testing the real-time radar data through the performance test model to obtain the target dynamic scene digital signal includes:

[0034] Performing a performance test on the real-time radar data through the performance test model to obtain an original dynamic scene digital signal;

[0035] The original dynamic scene digital signal is format converted according to a preset signal format conversion rule to obtain a target dynamic scene digital signal.

[0036] It should be understood that the simulated dynamic scene, digital model and receiver operating mode are combined to calculate the output signal processing waveform design and generate the corresponding dynamic scene target special signal I / Q data (ie, the original dynamic scene digital signal).

[0037] Specifically, it is converted into signal data that can be recognized by the electronic warfare receiver sampling and processing module according to a certain data format (i.e., the preset signal format conversion rules), and the electronic warfare receiver is controlled to switch the received data to the dynamic scene simulation analog I / Q data source, and receive the corresponding target special signal simulation I / Q data (i.e., the target dynamic scene digital signal).

[0038] Specifically, select the application platform of the receiver under test, set the platform movement mode and trajectory, antenna type and scanning mode; according to the main target objects in the working frequency band of the receiver under test, load the measured data of the corresponding target objects, and calculate the waveform design of the output actual combat target signal; according to the dynamic scene of the application platform of the receiver under test, superimpose the changes in the motion posture of the application platform and the influence of external electromagnetic environment interference noise, calculate and output the waveform design of the actual combat target signal under specific conditions; combine the working mode and number of channels of the electronic warfare receiver under test, and generate the corresponding dynamic scene target special signal I / Q data (i.e., the original dynamic scene digital signal).

[0039] Specifically, according to the data format that can be recognized and processed by the sampling and processing module of the receiver under test, the special signal waveform design software needs to convert the format of the special signal I / Q data (i.e., the original dynamic scene digital signal) according to the corresponding data format; set the working mode of the receiver under test to the signal parameter measurement mode, and make real-time adjustments to the parameters such as the frequency, pulse width, period and amplitude of the special signal, and output the special signal I / Q data corresponding to the ideal electromagnetic environment (i.e., the target dynamic scene digital signal); set the working mode of the receiver under test to the signal sorting and processing algorithm verification mode, and make real-time adjustments to the parameters such as the number of simultaneously arriving signals, time difference, phase difference and amplitude difference of the special signal, and output the special signal I / Q data corresponding to the complex electromagnetic environment (i.e., the target dynamic scene digital signal).

[0040] In the above embodiment, the real-time radar data is tested through the performance test model to obtain the target dynamic scene digital signal, which solves the problems of concentrated debugging workload, uncontrollable detection progress and slow technical iteration, and the receiver performance can be tested around the clock and in all regions.

[0041] Optionally, as an embodiment of the present invention, the process of inputting the target dynamic scene digital signal into a receiver to be detected for detection and analysis, and using the analysis result as the detection result of the receiver to be detected includes:

[0042] S31: inputting the target dynamic scene digital signal into a receiver to be detected to obtain a detected digital signal;

[0043] S32: verify whether the detected digital signal is the same as the target dynamic scene digital signal, if yes, execute S33; if no, take the existence of a fault in the receiver to be detected as the detection result of the receiver to be detected;

[0044] S33: Determine whether the detected digital signal meets the preset technical indicator requirements. If so, the qualified receiver to be detected is used as the detection result of the receiver to be detected; if not, the unqualified receiver to be detected is used as the detection result of the receiver to be detected.

[0045] It should be understood that the electronic warfare receiver under test (i.e., the receiver to be tested) receives analog I / Q data (i.e., the target dynamic scene digital signal) and performs signal parameter measurement and signal sorting and processing algorithm verification. The actual test signal parameter values ​​can be sent to a high-performance server to calculate the difference between the actual measured value of the receiver and the theoretical value set by the special signal waveform design software.

[0046] Specifically, according to the measurement error data results and technical index requirements (ie, preset technical index requirements) of the electronic warfare receiver under test (ie, the receiver to be tested), a performance evaluation report (ie, the test results of the receiver to be tested) is output.

[0047] It should be understood that the preset technical indicator requirements can be understood as pre-constructed signal parameter indicators.

[0048] In the above embodiment, the target dynamic scene digital signal is input into the receiver to be detected for detection and analysis, and the analysis result is used as the detection result of the receiver to be detected. This is not limited by the number of traditional special system signal sources, and the problem of the receiver can be discovered as soon as possible during the module-level debugging stage, as well as the optimization of the algorithm design. This solves the problems of concentrated debugging workload, uncontrollable detection progress, and slow technology iteration. The receiver performance can be tested around the clock and in all regions, which speeds up the iteration of technology, reduces the detection cost, and has great application value.

[0049] Optionally, as another embodiment of the present invention, the present invention analyzes the working principle of special signal waveform design, combines the technical characteristics of digital twin, special signal waveform design software and receiver processing algorithm, and uses visualization software technology to build realistic digital models of target signals of airborne, land-based and ship-based platforms for electronic warfare receivers, generates special signal waveforms containing measured data, application scenarios, target objects or interference noise and other information, and outputs I / Q data of various special signal waveforms in a flexible software definition mode, which is not limited by the number of signal sources of traditional special systems, and solves the problems of time conflict, slow project development progress and long development cycle when multiple projects are developed in parallel. The special signal waveform I / Q data generated based on realistic dynamic scenes is directly sent to the receiver sampling and processing module, and the receiver performance parameters and core algorithms can be tested and verified, so that the receiver problems and optimized algorithm design can be found in the first time in the module-level debugging stage, and the problems of concentrated project debugging workload, uncontrollable project progress and slow technical iteration can be solved. The performance measurement of electronic warfare receivers can be carried out all-weather and all-regionally, which speeds up the technical iteration speed, shortens the project development cycle, and reduces the R&D cost, and has good application value.

[0050] Optionally, as another embodiment of the present invention, the present invention combines the technical features of digital twin, special signal waveform design software and receiver processing algorithm, and uses visualization software technology to build realistic digital models of target signals of airborne, land-based and ship-based platforms for electronic warfare receivers, generate special signal waveforms containing measured data, application scenarios, target objects or interference noise and other information, and output I / Q data of various special signal waveforms in a flexible software definition manner, which is not limited by the number of signal sources of traditional special systems, and solves the problems of time conflict, slow project development progress and long development cycle when multiple projects are developed in parallel.
