PROBLEM TO BE SOLVED: To solve the problem that if automatic tracking of a mobile body fails, a transmitted radio wave is cut off and it becomes impossible to know the position and current state of the mobile body after failure and the cause of failure in tracking a helicopter.SOLUTION: A receiving system receives a radio wave from a mobile body. The receiving system comprises a camera 11, a receiving antenna 14, a supervisory monitor 12 which displays video transmitted from the camera 11, and a rotary unit 17. The camera 11 is installed near the receiving antenna 14. The camera 11 and the receiving antenna 14 can change their azimuth directions and up/down angles by the rotary unit 17. The camera 11 can output shot video in a direction in which the transmitted radio wave from the mobile body is strongest when received by the receiving antenna 14 to the supervisory monitor 12. As the shot video is displayed on the supervisory monitor 12, it is possible to confirm the current position of the mobile body and recover from failure in tracking easily. |
