Description

technical field [0001] The invention relates to the technical field of electronic countermeasures, in particular to a radar anti-interference detection and optimization system and method based on simulation technology. Background technique [0002] At present, when domestic scientific research or teaching units in the field of electronic countermeasures use radar simulators or small radars to conduct research and teaching of anti-jamming algorithms, the equipment needs to cooperate with a jammer in the process of algorithm verification research, and the equipment generates radar. The signal is radiated into the space. After receiving the radar signal, the cooperating jammer generates a certain pattern of jamming signal, which is sent back to the device through radiation; the jamming signal enters the device from the receiver, and the jamming effect is realized by digital processing. is generated and displayed on the screen of the display console; [0003] Among them, after ...

Problems solved by technology

[0003] Among them, after the algorithm verification personnel modify the DSP program, adding the anti-jamming algorithm needs to be compiled for a long time and then programmed into the DSP circuit, and then the new processing program is used to process the jamming signal of the jammer. At this time, the new The interference effect will be displayed on the desktop of the display control terminal; by comparing the interference effect of the display and control interface before and after the addition of the anti-interference algorithm, the effectiveness of the anti-interference measures can be judged, so as to realize the effectiveness verification of the anti-interference algorithm; however, in the above applications, exposed The following problems arise: First, radar simulators or small radars need to cooperate with jamming equipment, and cannot realize the closed loop of radar signal generation, jamming, and anti-jamming; The parameters are verified in real time, and the algorithm verification efficiency is low
