基于DSP和FPGA协同处理技术的波束控制设计

A Beam-steering System Based on Cooperative Processing of DSP and FPGA

目前雷达系统对波束控制系统的计算和配相速度的要求越来越高,如何有效地提高波束控制系统的计算和配相速度,同时减小硬件设计复杂度,提出了利用DSP的单指令多数据流(SIMD)特点对波控码进行优化计算的方法,以及采用FPGA对波控码进行并行配送的优化思想。通过验证,系统响应时间得到了显著改善。

The calculation and distribution speed of phased code in beam control system is required higher and higher. In this paper, two optimizing methods for calculation and distribution of the phased code is presented. In these optimizing methods, SIMD optimizing technology and row-orientation data distribution are used. The experiment results demonstrate that application of these optimizing methods is remarkably raising the performance of the beam control system.
