摘要：

The signal parameter estimation of polarization sensitive array mainly studies the joint estimation of DOA and polarization parameters via array sampling data. MUSIC algorithm can effectively estimate the DOA of signal source, but the resolution of MUSIC algorithm will be reduced or even invalid with low signal-to-noise ratio (SNR) and small signal interval conditions. This paper studies an improved MUSIC algorithm which can effectively estimate DOA of signal sources with low SNR and small signal interval conditions. At the same time, the joint parameter estimation based on the MUSIC algorithm is applied to uniform linear array. The simulation results show that the DOA of the signal can be clearly distinguished from the polarization domain and the spatial domain.
