摘要: 本文提出了一種基于十字架型陣列接收系統(tǒng)的二維高分辨率測向快速分維處理方法.它具有粗粒度的并行性,且運(yùn)算量大大小于二維直接處理方法或已有的其它分維處理方法.文中還給出了兩種改進(jìn)措施來減少分維處理所帶來的性能損失.最后,給出了部分計(jì)算機(jī)模擬實(shí)驗(yàn)結(jié)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. -
