[0063]
Further, the moving object detection sensor 34 performs vertical scanning and horizontal turning scanning using a multi-beam antenna from a direction orthogonal to the passing direction of the moving object, and determines the presence or absence of the aircraft based on the combined reception level obtained by both these scanning. , It is possible to three-dimensionally recognize the moving body, and easily recognize the passage of vehicles other than aircraft.
[0064]
Further, as the evaluation display system 4, a simulator system 44 is connected to the evaluation display device 42 via the information LAN, and a fixed airport model image is displayed in advance, and the evaluation display device is displayed on the model image. Since the moving object being captured output from 42 is displayed three-dimensionally and can be monitored from four directions, a plurality of controllers can monitor the same information at the same time, and it is possible to correct control operation errors. .
[0065]
Further, the simulator system 44 is provided with abnormality indicator lamps 76a to 76d, and when it is determined by the operation management device 41 that an abnormality is detected by the collision avoidance processing of the moving body, the abnormality is displayed. It is possible to do.
