Abstract
A dual line of sight forward looking infrared (FLIR) navigation and targeting system including two separate infrared turrets housing respective optical gimbal assemblies which simultaneously provide two independently controlled lines of sight, one of which has wide field(s) of view for implementing a pilotage function and the other has narrow magnified field(s) of view for implementing a targeting function. Both lines of sight are merged following individual temperature compensating image gain and level adjusting operations in an optical multiplexer assembly, the output of which is coupled to a single IR detector in the form of a focal plane array having time delay integration. Two separate FLIR video image signals are generated in a single common processor, one for pilotage and one for targeting which can be viewed simultaneously and independently. The processor is also utilized and integrated with a radar system.
