摘要：PROBLEM TO BE SOLVED: To obtain a radio wave arrival direction search apparatus for correctly finding the arrival direction of a radio wave in a short time.SOLUTION: The radio wave arrival direction search apparatus for determining the arrival direction of the radio wave emitted from a transmission source so as to search the transmission source for emitting the radio wave includes: an antenna for receiving the radio wave arriving from a predetermined angle range; a vehicle running and equipped with the antenna; and a search section for detecting the arrival direction of the radio wave having maximum electric field intensity among the radio waves received by the antenna each time the vehicle travels by a predetermined distance, and for determining that the radio wave is emitted in the arrival direction when the arrival direction is the same as the latest traveling direction of the vehicle.
