Research And Implement Of Near Airport Aircraft Flight Trajectory Monitor System

With the rapid development of China aviation industry, military aviation andcivilian aviation are constantly expanding the scale. Aviation security is animportant factor affectingthe development of the aviation industry and plays anincreasingly important role in the aviationcareer. In the field of military aviation,we hope the ground commanders can monitor the dynamic of the aircraft inreal-time, understand the operation of the aircraft, remind the pilot to make theright maneuvers timely, ensure flight safety.This dissertation researchs on a plane near-field flight monitoring system tosolve the problem of aircraft can not be monitor in the aircraft taxiing,taking offnear-field, landing stage which affects flight safety.Aircraft flight trajectorynear-field monitoring system is based on an intuitive visual control way totransmit nearly field-flying aircraft pose, flaperons, gear, rudder, etc working tothe flight commander in the form of the screen real-time, continuous, stable,effective complete monitor the takeoff and landing phases to ensure the flightsafety of the aircraft.According requirements of the airport and related scientific research aircraftnear-field flight path monitoring mission, gives technical requirements of threesub-systems include radar guidance tracking system, automatic tracking systemand status analysis and reproduce distribution system. Demonstrated the overalldesign of aircraft flying near-field monitoring system which adopt technology ofradar locked combined computer vision and image processing and recognition.Respectively derived working principle of three sub-systems include automatictracking system, automatic pose measuring system and status analysis andreproduce distribution system, proved the overall technical plan is feasible.Build a airplane near-field flight path monitoring system based on the aboveprinciple, to achieve the surveillance of an airport flight trajectory over the threecases include take off and landing on northern of airport, take off and landing onsorthern of airport and flying over the airport.The automatic tracking system includes three subsystems:(1) automatic tracking system;(2) automatic pose measuring system;(3) status analysis andreproduce distribution system, three subsystems have a clear division of labor,and merging to form a large integrated system, to be an organic whole.On the basis of system technical analysis, developed hardware system andsoftware system in a modular way, which includes a turntable, lens, imagetransmission and distribution, tracking module, position and attitudemeasurement module and key components module, formulated camera, turntableand the overall system calibration program, and completed inspection of theflight path monitoring system by test.
