Abstract:

To solve the problems in aircraft approaching, such as the blind zone of data-link covering and availability of real-time attitude and touchdown parameters by the control-tower, the aircraft landing detection and evaluation system is presented in the paper. The system is built based on the technology of multi-function electro-optical tracking. The composite structure and designed principle are also proposed. However, due to the limited field of electro-optical tracking, the electro-optical turntable aided by precision approaching radar (PAR) is used to guide the search for the landing aircraft. After the aircraft is captured stably, the target aircraft will be detected by the image processing algorithm. Then, the system switches to the tracking mode and the target aircraft will be locked. The attitude and flight path offset are then calculated. In the control-tower command and landing detection and evaluation, the system are proved to be of high practical value.

Key words: precision approaching radar, electro-optical equipment, landing detection, touchdown detection, landing evaluation
