一种基于DSP的信号分选硬件平台设计

A Kind of DSP-based Hardware Platform Design for Signal Sorting

在高密集复杂雷达信号环境下,雷达信号分选实时性是信号处理的一项关键技术,也是电子战领域一个有待提高的关键课题。利用高性能数字信号处理器(DSP)和现场可编程门阵列构建了一种双DSP信号分选硬件平台,极大地减少了分选的时间开销和分机系统的体积。实验结果表明,此方法极大地提高了信号分选的实时性。

In the environment of high density complicated radar signal,the real-time performance of radar signal sorting is a key technique for signal processing,as well as a key problem awaited improvement in electronic warfare domain.This paper uses a digital signal processor（DSP） with high performance and a field programmable gate array to construct a double-DSP hardware platform of signal sorting,which greatly reduces the sorting time and the volume of the subsystem.The experiment results show that the method greatly improves the real-time performance of signal sorting.
