摘要：
In this paper, we use the DOA estimation of timefrequency analysis on coprime polarization sensitive array, which can increase the number of signals estimated by multiple signal classification (MUSIC)algorithm and improve the degree of freedom of array. The polarization information can improve the estimation accuracy and help distinguish the signals with close wave direction. Time-frequency analysis can improve the estimation performance of multiple signal classification (MUSIC) algorithm in the case of low signal to noise ratio (SNR). The feasibility of time-frequency transformation in the coprime polarization sensitive array is proved, and MUSIC algorithm based on time-frequency analysis (P-TFMUSIC) is proposed to enhance the estimation performance of direction of arrival (DOA), and the function of the algorithm is verified by simulation.
