任意平面阵列的相关信号源高分辨测向处理技术

High Resolution Direction Finding Technique of Correlated Signals for Arbitrary Planar Array

针对空间谱估计MUSIC方法对相关信号源测向性能下降甚至失效的情况,对于任意设置的平面天线阵列,介绍了一种基于空间平滑和阵列内插思想的用于解决相干信号的方法,并提出了一种信号源方位角选择过程。对该方法进行了理论分析和计算机模拟。模拟实验结果验证了这种方法的正确性和可行性。

Because the spatial spectrum estimator MUSIC algorithm isn＇t very efficient for perfectly correlated signals, a good method which bases on the ideas of spatial smoothing and array interpolation is introduced and a selection process of signals angel of arrtival is proposed. This technique can be applied to arbitrary planar array, The performance of the technique is theoretically analyzed and evaluated by extensive computer simulations. The results prove that it is accurate and feasible.
