摘　　要：在S im u link仿真环境下,采用层次化方法建立了中脉冲重复频率(M PRF)机载PD雷达数字仿真系统,给出了仿真的系统框图和仿真结果。对该机载PD雷达在不同情况下的检测性能和抗干扰能力进行分析。考虑干扰分别从雷达天线的旁瓣和主瓣进入的情况,并采用自适应旁瓣相消技术后,得到了该雷达系统的检测概率曲线。仿真结果与理论计算结果相一致,从而正确地完成了系统的方案论证和性能评估,使雷达系统的设计更加方便、高效和优化。Based on Simulink environment, the digital simulation system for airborne MPRF PD radar has been established by using layered model, and the block diagram and simulation results are presented. The detection performance of the MPRF radar system is analyzed in different instances, and anti-jamming ability of the radar system is analyzed. The detection probability curves of the radar system are gained by using SLC with jamming arriving from side lobe and main lobe of the antenna. The simulation results are agreed with the theoretic results, so scheme demonstration and performance evaluation are completed correctly, the system can be designed more efficiently, conveniently and optimum.
