雷达传感器网络，包括双基地和多基地雷达，提供了几个业务优势，如降低脆弱性，良好的系统灵活性和增加雷达截面。然而，雷达间干扰抑制是分布式雷达传感器网络中的一个主要问题。本文提出了一种基于交叉匹配滤波的雷达间干扰抑制算法。该算法首先采用迭代滤波算法抑制雷达间干扰，然后对每部雷达分别进行匹配滤波。除了详细的算法推导外，还对上、下啁啾波形、部分重叠或反啁啾线性调频（LFM）波形以及正交频分复用（ODFM）啁啾分集波形进行了大量的数值仿真。仿真结果验证了算法的有效性。
Radar sensor networks, including bi- and multi-static radars, provide several operational advantages, like reduced vulnerability, good system flexibility and an increased radar cross-section. However, radar-to-radar interference suppression is a major problem in distributed radar sensor networks. In this paper, we present a cross-matched filtering-based radar-to-radar interference suppression algorithm. This algorithm first uses an iterative filtering algorithm to suppress the radar-to-radar interferences and, then, separately matched filtering for each radar. Besides the detailed algorithm derivation, extensive numerical simulation examples are performed with the down-chirp and up-chirp waveforms, partially overlapped or inverse chirp rate linearly frequency modulation (LFM) waveforms and orthogonal frequency division multiplexing (ODFM) chirp diverse waveforms. The effectiveness of the algorithm is verified by the simulation results.
