Armed Helicopters Day And Night Sighting System, Electrical System Design And Analysis

The Day/night Sight System of the Armed Helicopter is an important system for guidance and fire control of the helicopter. Its performance determines the precision of tracking and aiming weapon system, directly affects the hit probability of the missile. The Day /night Sight System is an integration of optical, mechanical and electronic components, including several electro-optical sensors. The designs of its electronic system is difficult due to the complexity of the various signals and compact structure, Many key points were met in engineering practice. This paper discusses the design of the electronic system of Day/night Sight System, some problems have been resolved such as electromagnetic interfererance, the transmission of sensitive signals and the interface of computer. These designs have been proved in the engineering practice with good effects.
