~1-5 is used to measure the direction of the radio wave transmission source 1-8. The direction measured here is the direction in which the angle obtained from the north pole 2-8 is measured when the direction of the radio wave source is measured from measurement points 2-2 to 2-4 in Figure 2. Become. The radio wave source calculation device 1-6 is the direction measuring device 1-1 to 1.
Based on the latitude and longitude of each direction measured from -5 and the location where each direction measuring device is installed, the latitude and longitude of all positions where each direction intersects (1-7 in Figure 2) is calculated using spherical trigonometry. The standard deviation of the rod is calculated from all the intersection points calculated by spherical trigonometry. Furthermore, only the intersections that fall within the standard deviation are considered valid intersections, and the intersections that deviate from the standard deviation are considered invalid intersections and are not used when ultimately determining the transmission source. In the FA standard deviation calculation process, the average of the intersections within the standard deviation is determined and determined as the radio wave source.
