Screened-Ratio-Principle-Based DOA Estimation Algorithm in Impulsive Noise Environment
基于Screened Ratio原理的冲击噪声环境下DOA估计算法

This paper present a new DOA estimation algorithm in impulsive noise environment. The algorithm uses firstly screened ratio principle to construct the correlation matrix of the array data and then implements the DOA estimation by MUSIC algorithm. In comparison with the Fractional Lower Order Moment (FLOM)-based algorithms, the proposed algorithm does not need the selection of the FLOM parameter. Computer simulations show that the algorithm is more robust and more accurate than FLOM-MUSIC algorithm.
