Abstract
In order to effectively counteract high-repetition-frequency jamming,a solution based on the analysis of the destructive mechanism of high-repetition-frequency jamming on laser guided radar signal processing was developed.The solution involves the use of randomly modulated laser waveforms and incorporates prior knowledge of the distance and velocity characteristics of the laser target indicator,target,and detector.A high-repetition-frequency jamming signal identification and discrimination method was designed based on adaptive overlapping wave gates,effectively controlling the impact of repetition-frequency jamming on the target acquisition process.It provided an end-to-end solution for combating high-frequency jamming,from waveform design to signal processing to effective target capture.The proposed solution was theoretically analyzed and experimentally verified.The results show that in different interference scenarios,the effective capture time is consistently below 0.2 s.The effective capture time is in the sub-second range,comparable to the typical capture time under no jamming background.This technology can effectively counteract fixed/random frequency jamming ranging from tens of Hertz to 250 kHz,enhancing the capability of guided weapons to counter high-repetition-frequency jamming.关键词
