A New DOA Estimation Method for Uncorrelated and Coherent Sources under Nonstationary Noise Fields

摘要：

A new direction of arrival (DOA) estimation method is proposed for uncorrelated and coherent sources under unknown nonstationary noise fields. The uncorrelated sources and coherent sources are resolved separately.In this way the output data of the array are used repeatedly,and more sources can be estimated.Compared with the conventional methods,the new method can resolved more sources using the same number of sensors. At the same time, the nonstationary noise can be translated into white noise,so the effect of the nonstationary noise is eliminated.Computer simulation results verify the correctness and effectiveness of the proposed method.
