A novel method of resolving velocity ambiguity in the pulse doppler radar

摘要

In this paper, a novel method of resolving velocity ambiguity in the pulse Doppler (PD) radar is proposed. By using multi-carrier-frequency waveform and Chinese Remainder Theorem (CRT), this method is able to overcome the velocity ambiguity. Furthermore, a modified algorithm with better robustness is deduced and its performances are analyzed in detail. Specific conclusions are verified with some simulation results.
