摘　　要：天基雷达可以在全球范围内探测和跟踪运动目标,目前在军用和民用方面受到了广泛的关注。天基雷达通常采用脉冲多普勒工作方式探测运动目标。脉冲多普勒雷达可分为高、中、低脉冲重复频率(PRF)3种类型。选取PRF是脉冲多普勒雷达设计的首要问题。分析了天基雷达检测运动目标的PRF设计相关问题,并对距离和速度模糊的解算方法进行了阐述。The space-based radar can detect and track moving targets on a global scale, and has aroused general concern in the fields of military and civilian applications. Pulse Doppler operating mode is usually used for space-based radar to detect moving targets. The pulse Doppler radars can be divided into three types.high pulse repetition frequency （PRF）,medium PRF and low PRF radars. It is the most important problem to select PRF in the design of pulse Doppler radar. This paper analyzes the correlative problem of PRF design for space-based radar to detect moving target, and expatiates the methods to calculate the distance and speed ambiguity.
