传统的解相干方法主要有空间平滑和子空间拟合两类,但这些方法或者阵列利用率低或者计算复杂度高,因此寻求计算量小且阵列利用率高的解相干测向方法有重要意义.该文基于前后向矢量重构理论,-The traditional decoherence methods spatial smoothing and subspace fitting into two categories, but these methods or array utilization rate is low or high computational complexity and therefore seek small amount of calculation and array of high utilization coherent finding method is important. This paper is based on the vector before and after Reconstruction,
