摘要：
The basic MUSIC algorithm can not effectively estimate the related-signal DOA, and when the antenna array has amplitude and phase errors, the algorithm will decline seriously in its performance. This paper improves the basic MUSIC algorithm by dividing the array steering vector properly and combining the new array steering vector with the low-dimension noise subspace method. The improved algorithm can correctly estimate the non-related signal DOA and the related. Meanwhile it can calibrate the array errors partially. This algorithm can be applied to electronic countermeasure. Simulation results verify the effectiveness of the algorithm.
