现代雷达信号处理设备的研制不仅对处理速度要求越来越高,并且对设备的体积和功耗也有苛刻的要求.为此,本文针对地面脉冲多普勒雷达信号处理的基本要求,研究以双片TMS320C25数字信号处理器构成的并行处理系统,完成对运动目标的检测.文中对并行处理系统的一些关键问题进行了较深入的研究,如解决输入数据的瓶颈效应,双片TMS320C25的同步协调问题等.此并行处理系统既能满足实时处理,又能大大缩小没备的体积和功牦.
The development of modern radar signal processing equipment not only demands higher and higher processing speed, but also has stringent requirements on the size and power consumption of the equipment.Therefore, this paper aims at the basic requirements of signal processing of ground-based pulsed Doppler radar, Chip TMS320C25 digital signal processor constitute a parallel processing system to complete the detection of moving targets.In the paper, some key problems of parallel processing system are studied in more depth, such as solving the bottleneck effect of input data, double-chip TMS320C25 synchronization and coordination Etc. This parallel processing system can not only meet the real-time processing, but also greatly reduce the size and power of equipment.
