Multistatic Radar Signal Coordinated Transmission and Processing for Suppressing Interrupted Sampling Jamming

This paper proposes a signal processing method based on multistatic radar coordinated transmission and processing aimed at suppressing Interrupted Sampling Jamming (ISJ). First, a signal model of multistatic radar is constructed where each node transmits a frequency-domain orthogonal and timedomain agile signal, and these signals can be combined into a continuous wave in time domain. Subsequently, a signal processing method is developed, which incorporates Multi-Channel Pulse Compression (MC-PC) and Multi-Channel Discrete Fourier Transform (MC-DFT) for signal accumulation. The method exploits discrepancies between the accumulation results of different pulse to suppress ISJ, while Density-Based Spatial Clustering of Applications with Noise (DBSCAN) is employed to determine plot centroid. Finally, simulations verify that the method exhibits good anti ISJ performance, successfully identifying and eliminating jamming, and allowing for the detection of the target.
