RADIO WAVE EMISSION SOURCE ESTIMATION DIRECTION DISPLAY APPARATUS AND RADIO WAVE EMISSION SOURCE ESTIMATION DIRECTION DISPLAY METHOD

PROBLEM TO BE SOLVED: To provide a radio wave emission source estimation direction display apparatus capable of easily recognizing a position of the display device's own and an estimation direction of a radio wave emission source relative to the position when a radio wave from the radio wave emission source is received.SOLUTION: A radio wave emission source estimation direction display apparatus includes: an antenna section for receiving a radio wave from a radio wave emission source; an arrival direction estimation processing section 7 for estimating an arrival direction of the radio wave; a GPS receiver 10 for acquiring positional information of the antenna section; an azimuth sensor 11 for acquiring azimuth information of the antenna section; a map display processing section 12 which acquires map information around the antenna section on the basis of the positional information acquired by the GPS receiver 10, calculates an arrival azimuth of the radio wave received by the antenna section on the basis of the arrival direction estimated by the arrival direction estimation processing section 7 and the azimuth information acquired by the azimuth sensor, superimposes the calculated arrival azimuth and the position of the antenna section on the map information, and outputs the map information; and a display section 13 for displaying a map indicating the arrival azimuth of the radio wave received by the antenna section and the position of the antenna section.
