The Simulation Analysis of DOA Estimation Based on MUSIC Algorithm

Array signal processing is a very important content in the field of signal processing and it's developing very rapidly in recent years. Direction of arrival (DOA) estimation is a key research. It has a broad prospect of application in radar, communication, sonar, seismology and other fields. Now the high resolution DOA estimation algorithm has achieved many important results, In this paper, we mainly studied and analyzed the classical multiple signal classification(MUSIC) algorithm, and the various factors which affect the estimation performance of the simulation, this provide the reference for the further study of MUSIC algorithm.
