摘　　要：在分析地面雷达探测巡航导弹杂波特性的基础上,构建了地面脉冲多普勒(PD)雷达的杂波重叠模型,通过对杂信比的仿真分析,明确了对脉冲重复频率(PRF)取值的影响及限制。从解模糊及减小盲区的角度,对地面PD雷达的检测准则进行了分析论证,然后利用遗传算法对PRF组进行了优选设计。仿真表明,通过合理的PRF组设计,地面PD雷达既可以解模糊,又可以在较大范围内克服盲区。From analyzing ground clutter characteristics of ground-based radar for detecting cruise missile （CM）, a clutter overlap model of ground-based pulse Doppler（PD） radar is established, and restriction and influence of overlaped clutter on pulse repetition frequency （PRF） values is made clear when PD radar detects CM by simulating clutter signal ratio（CSR） in this paper. Aiming at solving the ambiguities and minimizing the blind regions, a detection criterion of ground-based PD radar is demonstrated, then the PRF set are optimized by using generic algorithm. The simulation results show that ground-based PD radar can not only resolve range and velocity ambiguities, but also has a good capacity to overcome the blind regions in large scale regions by designing PRF set reasonably.
