摘　　要：文章讨论了星载降水测量雷达(SPR)重频设计要求和约束条件,并以GPM KuPR系统参数为例,研究了SPR重频设计的约束条件,提出和分析了几种重频设计方案。仿真结果表明一种自适应重频技术完全满足系统要求,并能获得最多脉冲积累数。In this paper, the requirements and restrictions of PRF design for SPR（ Space-borne Precipitation Radar） are discussed. Several PRF design schemes on the GPM KuPR system parameters are researched on the basis of analysis for these restrictions. Finally, simulations have shown that a variable PRF design technology is proved to fully satisfy the system requirements and multiple pulse integrations are obtained.
