摘　　要：介绍了一种脉冲多普勒雷达高重频测距的技术,对测距原理和处理算法进行了论述。以脉冲多普勒雷达系统为例,建立了雷达系统的仿真模型,对模型的组成部分:发射链路、接收链路、采样预处理部分进行了详细论述,并给出了各部分的仿真结果。通过仿真结果分析得知,高重频脉冲多普勒测距技术切实可行,并且具有算法简单、占用信息处理资源少和可在一定程度上提高杂波环境下对目标的检测能力等优点。A high frequency rang measurement technique for pulse doppler radar is introduced,the principle and algorithm of rang measurement are discussed. A pulse doppler radar system is taken as an example,the simulation model of radar system is established. The components of the model such as the transmission link,receiving link,analog signal sampling and preprocessing are discussed in detail. The simulation results of each part are given. The results show that the high frequency rang measurement technique for pulse doppler radar is feasible. The technique is characterized by simple algorithm and less processing resources,the detection ability of target in clutter background can be improved to some extent.
