摘要
为了改进目前检测雷达告警设备的多波段分立式雷达射频信号模拟器,采用PC104+CPLD设计了一种通用雷达射频信号模拟器,创新地设计了分频功率回退谐波抑制方法。根据电子对抗接收机的工作特性,模块化雷达射频信号模拟器的结构组成,并对各模块进行了优化设计。实践证明该模拟器具有良好的通用性和可扩展性。
To improve the available the multiband separated radar RF signal simulator for testing radar alarm equipment,a general radar RF signal simulator and frequency demultiplication power back-off method for harmonic suppression were designed with PC104＋CPLD..According to the working characteristic of electronic countermeasure receiver,the structural composition of radar RF signal simulator was modularized and every module was optimized.The actual application shows that the simulator haa good commonality and expansibility.
