Simulation and Realization of Avionics Countermeasure Equipment Testing Moving Target Radar Signal

分析了当前电子对抗装备信号场景模拟现状,针对运动场景下雷达目标信号模拟问题,提出了一种运动雷达目标信号模拟方法,根据设置的模拟场景解算三维空间下运动目标模拟信号参数,生成相应的PDW数据,并将其注入R&S SMW200A矢量信号源以合成两路最强的天线模拟信号。由于模拟场景具有可编辑性,该方法可在实验室环境下灵活快捷地模拟各种场景下运动辐射源信号,具有较高的模拟逼真度,同时由于采用PDW数据格式,大大压缩了数据量,能满足高脉冲密度长时间模拟的要求。

This paper analyzes the current situation of signal scene simulation of electronic countermeasure equipment.Aiming at the problem of radar target signal simulation in moving scene,a moving radar target signal simulation method is proposed.According to the preset simulation scene,the simulation signal parameters of moving target in three-dimensional space are calculated.The corresponding PDW data is generated and injected into the R&S SMW200A vector signal generator to synthesize the two strongest antenna analog signals.Due to the editability of the simulated scene,this method can simulate the moving radiation source signal in various scenes flexibly and quickly in the laboratory environment,and has a high simulation fidelity.It can meet the requirements of high pulse density and long time simulation.
