Space-based Satellite Reconnaissance Array Signal Processing Simulation Model

High resolution direction-finding using array signal processing plays an important role in the new electronic reconnaissance satellite system. Several algorithms,such as MUSIC ESPRIT,WSF,FOC - MUSIC,are researched in this paper. The analysis of these algorithms principle and the comparison of their performance from the point of view of engineering are given too. In this paper,analyse the effect of Doppler shifting to directing-fmding and the error to the location,and give the method to solve these problems. At last,a project of direction-finding system is presented.
