摘　　要：对雷达发射信号和目标三维模型进行了精确建模,计算了目标特定时刻的姿态角、运动信息、距离延时等信息。利用高频电磁软件仿真雷达静态散射截面积数据,模拟得到的目标中频回波信号不仅包含幅度相位信息,还有目标的极化特性、频率特性、幅度起伏特性等目标特性。为进一步研究跟踪雷达和目标回波特性提供了方法和数据支撑。The signals tramsmitted by radar and the three-dimensional model of target are accurately modeled,and the attitude angle,motion information,distance delay and other information of the target at a specific moment are calculated.The static radar cross section(RCS)data are simulated by using high-frequency electromagnetic software,and the simulated target intermediate frequency(IF)echo signal contains not only amplitude and phase information,but also target characteristics such as polarization,frequency and amplitude fluctuation,etc.,which provides the method and data support for further research into the racking radar and target echo characteristics.
