摘要
文中介绍了一种新的雷达信号模拟发生器,采用直接数字频率合成技术(DDS),利用高速数字信号处理器(DSP)和复杂可编程逻辑器件(CPLD),产生幅频可调的基带信号,同时可产生目标距离、速度等参数可调的脉冲多普勒雷达回波信号。
This text introduces a new radar signal generator. That adopts the technology of DDS and uses DSP and CPLD to produce the basal signal whose extent and frequency can be change. In addition, it produces pulse echo signal, in which the parameter of object's distance and velocity can also be changed.
