ELECTRONIC SUPPORT MEASURES PHASE INTERFEROMETER DIRECTION FINDING SYSTEM FOR THE DIRECTION ACCURACY IMPROVEMENT

摘要

The present invention relates to an E.S.M. phase interferometer system with improved direction finding accuracy and, more specifically, to a phase interferometer direction finding system which divides an entire reception frequency range into relatively low direction finding accuracy and high direction finding accuracy and can change an antenna arrangement interval according to the areas. An aspect of the phase interferometer direction finding system comprises: an antenna array in which multiple directions finding antennas are disposed at regular arrangement intervals; a reception antenna which receives a signal; a phase detecting unit which detects a phase of the signal received by the antenna array; a reception unit which receives the signal received by the reception antenna; a switch unit which switches connection states of the direction finding antenna and the reception antenna to each other; and a control unit which controls the switch unit. In addition, another aspect of the phase interferometer direction finding system comprises: an antenna array in which multiple directions finding antennas are disposed at regular arrangement intervals; a reception antenna which receives a signal; a phase detecting unit which detects a phase of the signal received by the antenna array; a reception unit which processes the signal received by the reception antenna; a switch unit which switches connection states of the direction finding antenna and the reception antenna to each other; a switch unit which switches connection states of the direction finding antenna and the reception antenna to each other; and a control unit which controls the switch unit.
