본발명은레이더신호처리기술에관한것으로서, 더상세하게는바이스태틱레이더환경에서재머로인한 DOA(direction of arrival)를구별하고표적 DOA와 DOD(direction of departure)를추정하는방법및 장치에대한것이다. 본발명에따르면, 재머가존재하고임의의 2차원또는 1차원안테나배열을갖는바이스태틱레이더환경에서수신신호로부터표적에의한 DOA(Direction Of Arrival)와재머로인한 DOA를구별할수 있다.
Abstract:
The present invention relates to a code tracking technology and, more specifically to, a code tracking system and a code tracking method of a multiplexed binary offset carrier signal which is a representative civil positioning signal of a global navigation satellite system. According to the present invention, provided is a code tracking system which reduces the ambiguity of a code tracker by using one multiplexed binary offset despreader and one binary offset carrier despreader, in contrast as a conventional code synchronization tracker for a multiplexed binary offset carrier signal uses a multiplexed binary offset carrier despreader only, and thus false lock point can be reduced remarkably within one chip based on an accurate synchronization point of time basis.
