基于单辅助源的阵列幅相误差校正方法

Research of Array Gain and Phase Error Correction Algorithm Based on Single Auxiliary Source

研究了一种基于辅助信源的阵列校正算法。当阵列存在不依赖方位的幅相误差时,用本文的方法对阵列进行校正,校正后的各个阵列各个通道的增益和相位均达到一致,对修正后的阵列采用MUSIC算法得到了准确的波达方向估计值,仿真试验验证了该方法的有效性和可行性。

An array gain and phase error correction algorithm based on single anxiliary sourse is presented and discussed in this paper.The gain and phase of all arrays and channels are coherent after correcting.The arrays are modified to estimate the DOA with the MUSIC algorithm and get the more accurate DOA of the signals.The simulation results are presented to show the feasibility and validity of the algorithm proposed.
