摘要
高分辨测向算法主要包括MUSIC算法、最小范数法、前向平滑算法和修正MUSIC算法等。无论是针对独立源或是相干源,在没有考虑阵元的幅相误差的情况下,这些算法都能准确进行到达方向(DOA)的估计。主要考虑存在幅相误差时,两类高分辨测向算法(最小范数法和前向平滑算法)的DOA估计性能。最后,给出了计算机仿真结果,并对幅相误差对算法的影响作了性能分析。
The high resolution direction-finding（DF） algorithms mainly includes MUSIC algorithm, min-norm algorithm,forward smoothing algorithm and modified MUSIC algorithm,etc.Whether the signal is independent or correlative,under the circumstances of no considering the amplitude and phase error,these algorithms all can exactly perform the estimation of direction of arrival （DOA）.This paper mainly considers the DOA estimation performance of two kinds of high-resolution DF algorithms（min-norm algorithm and forward smoothing algorithm） when the amplitude and phase errors exist.Finally,the computer simulation result is presented,and the performance analysis of these algorithms is performed when the amplitude and phase errors exist.
