METHOD TO AVOID AIRCRAFT COLLISION WITH OBSTACLE AND ASSOCIATED DEVICE Russian patent published in 2008 - IPC G08G5/04 

FIELD: transportation.

SUBSTANCE: invention is related to forecasting likelihood of aircraft collision (flying around) obstacle. The essence of invention is that the type of obstacle movement trajectory (straight line or circle) is determined by obstacle coordinates and the shortest distance from air craft to approximate obstacle trajectory is calculated. Hence, likelihood of flying around or collision may be forecasted. Forecasting device consists of image detectors unit comprising two spaced and identical lenses with image detectors, calculator including obstacle image analyser and trajectory definition and approximation monitoring module, collision analysers in case obstacles move directly or describe a circle accordingly, OR logic generating collision signal and signal switch generating t_col signal (time left to collision) are also included into this device.

EFFECT: improvement of air craft collision data reliability and forecast efficiency.
