摘要：
In his paper we propose a novel multi-jamming direction finding method of space-borne antenna. Firstly, we present single-snapshot DOA estimation algorithm in frequency to estimate the DOA of multiple targets, and then use the nulling projection matrix to make the stronger signal not so strong in order that we can estimate the weaker signal according to the prior accurately estimated DOA. The presented algorithm solves the problems of DoA estimation exactly. Simulation results and performance analysis demonstrate that the algorithm is effective and feasible.
