RF PROXIMITY FUZE SENSOR FOR DIRECTION FINDING AND METHOD FOR FINDING DIRECTION THEREOF

摘要

The present invention relates to a proximity fuse sensor, and more specifically, to a full-wave proximity fuse sensor for direction finding to find the direction of an air target moving at a high speed by transmitting and receiving radio signals, and a method thereof. According to the full-wave proximity fuse sensor for direction finding and the method thereof, it is possible to find the distance range and the direction of an air target moving at high speed by transmitting and receiving signals which are digitally phase-modulated through the bi-phase shift keying method and applying a code correlation technique and a direction finding algorithm with multiple range gates.
