| 摘要: |
| 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. |

| Abstract: |
| In the modern radar signal processing equipment, the speed of signal processing is more and more high, however the volume and the power is more and more small. According to the elemental function of ground pulse doppler radar signal process, this paper developed a parallel processing system based on two Texas Instrument, TMS320C25 signal processing chips to realize the detection of ground moving target. Some key problems in the parallel processing system such as the problem of data input and the concordant of two processor are researched. The system can realize the real-time processing, the volume and the power of the system is decreased. |
