基于CPLD的天气雷达信号处理器的设计实现

Design and Implementation of Weather Radar Signal Processor Based on CPLD

信号处理器是常规天气雷达数字化系统的关键部件.利用复杂可编程逻辑器件(CPLD)产生整个信号处理器时序控制逻辑信号,通过移位运算,直接进行硬件积分处理.实现雷达信号的采集、处理、质量控制、天线控制以及数据传输等功能,并成功应用在常规天气雷达数字化改造系统中,工作稳定,性能良好.

As the key component of a conventional weather radar digitizing system,signal processor adopts a Complex Programmable Logic Device （CPLD） to generate the timing control signals so that the hardware integration processing is directly performed through bit-shift operations,which can be used to realize such functions as signal acquisition,processing,quality control,antenna control and data transmission.It has been successfully applied in the weather radar digitizing system,with stable operation and good performance.
