基于剩余定理和一维集法的PD雷达解模糊处理

摘要

The problems of range ambiguity and velocity ambiguity are common issues in pulse Doppler radar, At present, the mature algorithms of ambiguity resolution for PD radar include residues' difference look-up table method, remainder theorem and one-dimensional set algorithm. Each of these algorithms has merits and shortcomings, and it is suitable for different situations of ambiguity resolution. According to the characteristics of range ambiguity and velocity ambiguity, and combining with merits and shortcomings of ambiguity resolving algorithms, the method for the resolution of range ambiguity using remainder theorem is discussed, and the method for the resolution of velocity ambiguity using one-dimensional set algorithm is also presented.%脉冲多普勒雷达在目标检测时常常存在距离和速度模糊问题,目前比较成熟的解模糊算法有余差查表法、剩余定理和一维集法.这几种算法各有优点和不足,适合不同的解模糊情况.根据距离、速度模糊的特点结合算法的优缺点,这里利用剩余定理解距离模糊,一维集法解速度模糊.
