基于数据共轭重排修正的传播算子DOA估计算法

A Modified Propagator Algorithm for DOA Estimation Based on Conjugate Data Rearrangement

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DOA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,证明该算法在快拍数有限的情况下,可明显提高信号DOA估计的性能。在不增加运算量的条件下算法性能优于MUSIC算法。

In this paper, the conjugate data being rearranged is amplified on 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 algorithm, and its computational complexity is about equal to that of the typical propagator algorithm.
