IPC: G01S3/46
Filed: 2000-09-21
Abstract: PROBLEM TO BE SOLVED: To overcome the problems of a prior art such that radio interference easily occurs due to a plurality of incoming signals of the same frequency as the incoming signals at a receivable level or more from all the directions from close and long distances are received by antenna elements for finding direction with directionality of a wide beam width within a vertical plane and non-directionality within a horizontal plane and that it is difficult to even hear the demodulated sound of reception signals from a close-distance monitoring range necessary for the function of radio monitoring through the use of a radio direction finder especially in the case of radio interference with the presence of strong reception signals from the same direction more from close distances than from long distances. SOLUTION: An auxiliary antenna element for detecting sound with a predetermined downward directionality of a narrow beam width within a vertical plane is provided above the center of the antenna elements for detecting direction arranged in a circumference. By switching audio demodulation to reception signals from the auxiliary antenna element for detecting sound at radio interference, it is possible to hear the demodulated sound of incoming waves from close distances with stronger sound.
