摘要: 本文提出了一种新的阵处理方法,此法无需进行特征值分解(EVD)和多维最优化处理。因此它计算简单、易于实时处理,而且适合于相干源存在的情况。文中将新方法与PROJ(1991)和Yeh(1987)两种方法作了比较;还给出了模拟结果。

Abstract: A new array processing method is presented. The method is computationally simple and beneficial to real-time processing, because it dose not require eigenvalue de-composition (EVD) and multi-dimensional optimizing processing. The method is also suitable for the coherent case. It is compared with PROJ method and Yeh s method (1987). Simulation results are given. -
