DEVICE FOR ESTIMATING AZIMUTH OF RADIO STATION, DEVICE FOR ESTIMATING AZIMUTH OF RADIO STATION AND EMITTING RADIO WAVE, AND METHOD OF ESTIMATING AZIMUTH OF RADIO STATION

摘要

PROBLEM TO BE SOLVED: To provide a device for estimating an azimuth of a radio station capable of highly precisely estimating the position of the radio stations, to provide a device for estimating the azimuth of the radio station and emitting radio waves, and to provide a method of estimating the azimuth of the radio station.;SOLUTION: The arrival direction of the desirable radio wave are estimated by an array antenna 1, frequency detection means 2 and radio wave arriving direction detection means 3. A position of the radio station estimation means 5 of ray trace method estimates the position of the radio station by the ray trace method based on the arrival direction of the estimated radio wave, and the 3-D map data from altitude/map database 4 provided with the 3-D map data.;COPYRIGHT: (C)2006,JPO&NCIPI
