一种脉冲多普勒雷达解模糊新算法

A New Algorithm for PD Radar Ambiguity Resolution

模糊问题是脉冲多普勒雷达的固有问题 .目前常用的解模糊算法是孙子定理方法和一维集算法 .本文提出了一种新的解模糊算法 ,即群算法 .这种算法对测量误差不敏感 ,而且既可以解距离模糊又可以解多普勒模糊 ,所以它的性能优于孙子定理算法 .另一方面 ,由于使用了查找表 ,群算法的计算量比一维集算法小 ,因而更适合实时处理 .

Ambiguity is a inherent matter of PD (pulse Doppler) radar.The Sunzi algorithm and the cluster algorithm are two popular algorithms for ambiguity resolution.In this paper,a new ambiguity resolution algorithm ,i.e.group algorithm,is proposed.The new algorithm has better performance than the Sunzi algorithm because it can rectify the measurement error and can resolve Doppler ambiguity as well as range ambiguity.And thanks for the use of look up table,the group algorithm fits real time signal processing better than the cluster algorithm.
