Abstract

Abstract:

In a pulse, jammers precisely replicate and rapidly forward to form interrupted-sampling repeater jamming (ISRJ), which seriously affects the performance of radar. Aiming at this problem, this paper starts from waveform design and filtering and then proposes a method of frequency agility waveform combined time-frequency filter to suppress ISRJ. Firstly, the conventional linear frequency modulation (LFM) signal is divided into several segments and randomly rearranged to construct the intra pulse frequency agility waveform. Secondly, the time domain projection component is obtained by time-frequency analysis of the echo signal, and the optimal segmentation threshold is calculated by OTSU algorithm to extract the undisturbed signal segment. Finally, a filter is constructed by convolution operation to perform band-pass filtering on pulse pressure output to preserve the real target and achieve the interference suppression. Simulation results show that the proposed method can effectively suppress the ISRJ under the condition of high jamming power and low signal-to-jamming-and-noise ratio, which greatly improves the radar anti-jamming performance.

Key words: electronic countermeasures, interrupted-sampling repeater jamming (ISRJ), frequency agility, time-frequency filtering
