摘　　要：针对寄生调幅是影响 FMCW毫米波雷达作用距离的重要因素 ,讨论了中频滤波器在 FMCW毫米波雷达系统中的作用 ,研究了滤波器性能与雷达作用距离的关系 .根据分析表明 ,对中频滤波器进行了 CAD优化 。The function of IF filter in the FMCW millimeter-wave radar system was discussed considering that parasitic AM was the main factor that affects the detecting range of FMCW millimeter-wave radar. The dependence of the detecting range of the radar on the performance of the IF filter was also analyzed. The results show that the detecting range of the radar is increased after the IF filter is optimized with HP CAD.
