中频信号模拟器是相控阵雷达不可缺少的一个分系统，其设计和实现上有着独特的特点。采用模拟控制处理器实时接收雷达主控机的控制字的方法，按雷达天线波束指向，判断当前目标是否在波束内。若在波束内，则按目标距离和工作模板产生相应距离和波形的模拟回波。模拟器用于雷达系统的自动化监测、雷达各分系统对接试验和模拟试验、操作人员的培训、雷达系统的功能测试和检查以及模拟动态飞行目标。%The intermediate frequency signal simulator is an obbligato subsystem of phased array radar,which has a unique characteristic in desgn and implementation. The method that analog control processor receives the control words from host control equipment of radar is adopted to judge wether the target is in the beam according to the beam pointing of radar antenna. If the target is in the bem,the analog echo of corresponding distance and waveform is generated according to the target distance and working template. The simulater is applied to automatic monitoring,subsystems connection test,simulation test,operator training, radar system functiom test,radar system function testing and inspectjion and dynamic flight target simulation.
