摘要
提出了一种基于阵列流型替换的宽带非相干DOA估计新方法。比较了宽带非相干(ISSM)方法与本文方法在分辨两个相邻较近信号源时的性能。仿真表明,本文方法大大降低了信噪比门限,其它性能也优于ISSM方法。
A new incoherent DOA estimation algorithm for wideband sources is introduced. The method is based on the array manifold replacement. The capability of the method for resolving two closely spaced sources is compared with that of the incoherent signal subspaee method (ISSM). Simulation results demonstrate the performance of the method is superior to that of the ISSM.
