摘　　要：在战场电磁环境中,机载雷达告警设备接收到的目标雷达信号随两者相对位置及相对运动变化而变化,为了实现告警设备测试时的逼真战时电磁环境的模拟,基于现有飞行位置数据,外推得到后续载机位置信息,依此解算两者位置变化。基于载机位置信息的变化,解算两者的速度变化;通过位置变化调整产生信号的功率,通过速度变化调整产生信号的频率,实现对雷达信号模拟器发射信号的调制,为告警设备的测试提供动态环境。In the battlefield electromagnetic environment,the target radar signal received by the airborne radar warning device changes with the relative position and relative motion of the two.In order to solve this problem,this paper extrapolated to obtain the subsequent carrier position information,and then solved the position change of the two based on the existing flight position data.Based on the change of the position information of the carrier,the speed change of the two was solved;the signal was generated by the position change adjustment.We adjusted the frequency of the signal generated by the speed change,and realized the modulation of the transmitted signal,and provided a dynamic environment for testing.
