Phase-coded Radar Performance And Applied Research

Phase-coded radar is playing a more and more important role in the radar field because of its quality of spreading spectrum.This paper discusses the possibility of using phase-coded technology in the long distance radar, which mainly faces the problem of signal sidelobe in the large dynamic range, and the problem of getting along with the phased array technology. To the first one, the method of new sidelobe-suppression filter and the method of cutting big signals from the echo are put up, and the result is fine. To the second one, get the echo without earth clutters, and send it to the adaptive system as the input signal, so that the best result can be reached. Finally the influence of the bad signal is given.
