摘　　要：根据雷达LFM脉冲压缩的基本原理及实际雷达脉压模块的频率特性测试数据,通过MATLAB仿真对比分析了理想匹配滤波器模型与实测模型的频率特性、脉压输出结果及抗有源压制干扰的性能。对比结果表明,传统的基于理想模型的LFM脉冲压缩仿真不能真正准确反映雷达脉压模块的性能,而基于实测数据模型的仿真能很好地解决这一问题,这为雷达系统的分析与设计及性能评估提供了重要参考。According to the basic principle of radar LFM pulse compression and the frequency characteristic data of the actual radar pulse compression module, the frequency characteristic and the anti-jamming capability between ideal match filter and real test model are analyzed by MATLAB simulation. The result indicates that traditional LFM pulse compression simulation based on ideal model cannot reflect radar pulse compression module accurately, and the simulation based on real test model can solve this problem. This research can provide important reference for the analysis and design of radar system and its performance evaluation.
