A Staggered PRF Coherent Integration for Resolving Range-Doppler Ambiguity in Pulse-Doppler Radar

In this paper, a staggered Pulse Repetition Frequency (PRF) coherent integration based on phase/time compensation algorithm in the receiver is proposed. Two staggered PRFs are used to extend blind Doppler frequency. The phase/time compensation algorithm is applied for coherent integration of non-coherent pulse-trains. As a result, the Doppler frequencies of targets are determined.
