An algorithm of resolving the range ambiguity using a single PRF

A new algorithm of range ambiguity resolution is presented which is substantially different from previously proposed algorithms. The algorithm utilizes a constant pulse repetition frequency (PRF). Firstly, a merit function is designed according to the moving characteristics of the targets. Secondly, range ambiguity resolution is achieved by minimizing the merit function. Numerical simulation results indicate that the proposed algorithm can resolve the range ambiguity efficiently using a single constant PRF.
