本专利描述双视场电光扫描系统,它用大视场捕获目标,再用小视场高精密跟踪。已知的电光扫描系统,主要功能都是在其视场内搜捕目标,捕获后进行跟踪。其中有红外跟踪器,它指向目标的红外能量。这种接收器接收到目标能量后可连续跟踪目标,获 This patent describes a dual-field electro-optical scanning system that captures a target with a large field of view and then tracks it with a high precision in a small field of view. The known electro-optical scanning system, the main function is to capture the target within its field of view, capture after tracking. Among them are infrared trackers, which point to the target’s infrared energy. This receiver receives the target energy can be continuously tracked target, won
