New algorithm for PD radar ambiguity resolution

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 by using of look-up table, the group algorithm fits real time signal processing better than the cluster algorithm does.
