摘要

利用超宽带雷达进行灾后生命搜救正在成为救灾手段的重要方法之一。其中对雷达回波信号数据的实时采集和存储是最重要的环节之一。但是由于DSP的工作时钟和A/D的采样速度不同,而采用FIFO作为两者的接口,从而提高系统的效率和稳定性。文中介绍了以TMS320VC5509为核心处理器,基于FIFO和DSP的超宽带搜救雷达数据采集系统的硬件和软件设计。实验结果表明,该系统具有速度快、稳定性高、控制方便等特点。
Using UWB Radar to search and rescue life is becoming an important means of disaster relief. The data acquisition and store for radar echo signals is one of the most important links. However the working clock of DSP and the sampling rate of A/D converter are different,so that FIFO is taken as the interface between these two,thus to improve the efficiency and stability of the system. This paper describes hardware and software design of data acquisition system for UWB search and rescue radar,which adopts TMS320VC5509 as the core processor and is based on FIFO and DSP. The experiment results and the practical application show that this system possesses the characteristics of fast speed,high stability and convenient control.
