Abstract:

A wide comparison is presented of high resolution Direction of Arrival (DOA) methods. The development of DOA estimation approaches is reviewed briefly. In order to study their performance clearly, more than 30 methods were divided into 5 groups, which are conventional methods, parametric modeling methods, subspace based methods, deconvolution methods, and other methods. Ten typical methods of them were studied in resolution and precision respectively. Based on a unitized simulation model, they were compared through statistical analysis. Furthermore, several criteria for application were proposed to judge their practicality. At last, MUSIC, Mini Norm are considered to be worth the most promising methods for utility while WSF, etc. to be worth theoretical studying.

Key words: high-r esolut ion DOA estimation, a rr ay pr ocessing, sta tistical analysis
