Abstract

A novel precise radar target ranging method based on echo phases and slip matching of envelopes is presented in this paper. The method provides a high precision with root-mean-square error at sub-wavelength level, and it only requires envelopes of the echo pulses. The difficulty is matching procedure of envelopes. According to the principle of resolving ambiguous phases based on slip matching of envelopes, some restraint conditions for ambiguity resolution are proposed, and the theory of extracting ambiguous Doppler phases from wideband radar echoes is provided. The method provides a more convenient and precise way to resolve ambiguous phases, and the experiments have validated the performance of ranging capability.
