摘要
研究了基于空时联合阵列信号处理的ESM系统,该系统不仅能够提高ESM系统的方位测量精度,而且能够处理同时到达信号。给出了系统组成方案,讨论了基于特征值分解的阵列信号处理算法,分别对非相干、相干信号的DOA估计算法进行了研究,给出了仿真结果。
This paper discusses the ESM system based on space-time combined array signal processing,which can not only improve azimuth measurement precision of ESM system, but also process the simultaneous arrival signal,gives the system composition,discusses the algorithm of array signal processing based on the eigenvalue resolution, studies the DOA estimated algorithm of uncoherent signal and coherent signal,gives the simulation result.
