雷达信号检测中解模糊的改进算法

摘要

模糊问题是脉冲多普勒雷达在信号检测时存在的固有问题,为了解决模糊问题,雷达一般采用多重脉冲重复频率（PRF）的工作方式。对于这种体制的雷达,目前常用的解模糊算法有孙子定理方法、一维集算法和查表法。主要阐述了一种基于一维集算法的改进算法及其实现步骤,并给出了利用该算法解距离模糊的仿真结果。%The ambiguity problem is the inherent matter in signal detection of pulse Doppler radars.For resolving the ambiguity problem,a multiple pulse repetition frequency（PRF） mode is usually used in the radar,and several methods have been proposed including the China Remainder Theory,the cluster algorithm and the lookup table method.This paper describes an improved method based on the cluster algorithm and its implementation steps,then the simulation results are given.
