摘要
针对国产BWDSP100处理器的性能和特点,提出了由4片BWDSP100处理器芯片构成的任务式并行信号处理系统,满足无源雷达大运算量的信号处理算法要求。该系统并行实现波束形成、自适应干扰抑制、长时相干积累和目标检测处理等。分析了雷达的主要信号处理模块在系统中的实现算法,估计了其运算量。实际工程应用表明该多片数字信号处理并行系统应用于无源雷达系统中,满足了雷达信号处理开放性、可扩展性的要求,提升了无源雷达系统的性能。
Aiming at the performances and characteristics of homegrown BWDSP100 processor,this paper puts forward the task-type parallel signal processing system consisting of four BWDSP100 processor chips,which meets the requirements of large computation amount signal processing algorithm for passive radar.Beam forming,adaptive interference suppression,long time coherent accumulation and target detection processing,etc.are implemented in the system in parallel.This paper analyzes the realization algorithm of main signal processing modules of radar in the system,estimates its computation amount.The practical engineering application shows that the multi-digital signal processing parallel system applied to passive radar system meets the requirements of open and expansibility for radar signal processing,which enhances the performances of passive radar system.
