General Analysis for Vehicle-based Object Identification Optical System

摘要

Vehicle-based object identification optical system using laser carrying wave radiated by high-power semiconductor lasers as carrier wave for transmitting signal, and it is co-operative system which his carrying wave can return. The modulating return wave of the system uses reflection prism is stable, when the detectors of all-oriented photoelectric receiver detect the key-code of identification of friend or foe, electrical machinery will drive the reflecting prism to revolve in order to form modulating return wave. To inspect reliable return wave signal and solve strong background lights disturb as while as adapts to changeable detecting technique problem of APD photo-electric detector, the system adopts obscure noise compensation and signal identification technique controlled by-computer in APD photo-electric system.
