摘要: 本文提出了一种基于十字架型阵列接收系统的二维高分辨率测向快速分维处理方法.它具有粗粒度的并行性,且运算量大大小于二维直接处理方法或已有的其它分维处理方法.文中还给出了两种改进措施来减少分维处理所带来的性能损失.最后,给出了部分计算机模拟实验结果.Abstract: A fast separable approach based on a cross array is presented which has coarsegrained parallelism. Its computational load is far less than that of the two-dimensicmal direct processing method and other existing separable approaches. In order to compensate for the performance degradation due to separable processing, two postprocessing schemes are also proposed. Some computer simulation results are provided for illustration in the end.
