修正的传播算子方位估计算法及去相关性能分析

A modified propagator algorithm for direction estimation and analysis of relativity performance

将数据共轭重排的方法引申到传播算子算法中,提出了修正的传播算子方位估计算法.从理论上论证了这种引申的合理性.通过理论分析和数值仿真,证明了该算法在快拍数有限时可明显提高信号的方位估计性能.在不增加运算量的条件下,该算法明显优于MUSIC(Mumple SignalClassfication)算法.

The conjugate data being rearranged is applied in the propagator algorithm, and the modified propagator algorithm is presented, Through theory analysis and simulation, this algorithm can obviously improve the performances of the signal DOA estimation when the snapshot number is limited. Moreover its performance is better than MUSIC （Mumple Signal Classfication） algorithm, and its computational complexity is about equal to that of the typical propagator algorithm.
