摘　　要：研究高分辨双极化雷达射频仿真问题。双极化雷达射频仿真需同时仿真目标回波信号的同极化分量和交叉极化分量,但传统仿真方法仅能仿真单一极化分量,不能满足双极化雷达仿真需求。为解决上述问题,首先研究分时双极化雷达工作原理和高分辨雷达目标回波仿真方法,在此基础上提出一种基于目标极化散射矩阵的双极化雷达目标回波仿真方法,给出采用DRFM技术的射频仿真系统实现方案,并通过仿真分析验证了方法的正确性。Research radio frequency（RF） simulation of high-resolution dual-polarization radar. In the simulation for dual-polarized radar, both co-polarized and cross polarized component in echo signal are needed. But the tradi- tional RF simulation method cannot be applied in high-resolution dual-polarization radar, since there is only co-po- larized component in echo signal. To solve this problem, on the basis of research on the principle of time-sharing du- al-polarized radar and echo simulation method for high resolution radar, an echo simulation method for dual-polar- ized radar has been proposed based on the target polarization scattering matrix, and the implementation of RF simula- tion system by DRFM technology has been given. The method was verified by simulation analysis.
