The invention discloses an enhanced airport scene monitoring system, which comprises a passive scene monitoring module, an air space active detection module, a ground active detection module, a monitoring module and a guide module, wherein the passive scene monitoring module is used for acquiring positions of all airplanes and vehicles provided with required airborne / vehicle-mounted equipment; the air space active detection module is used for detecting positional information of the airplanes in air; the ground active detection module is arranged at an accident-prone position and is used for actively detecting the positions of the airplanes close to a key region; the monitoring module is used for receiving the information of each module and judging whether warning action is implemented; and the guide module acts under the control of the monitoring module. Through the monitoring system, the problem of limitation that the conventional passive scene monitoring system completely depends on the airborne / vehicle-mounted positioning equipment of a monitor object can be solved, the capability of the system of detecting a moving object provided with no airborne / vehicle-mounted equipment or with abnormally working equipment is enhanced, and the capacity of the system of quickly processing emergency safety accidents is enhanced.
