Abstract

Optical imaging guidance technology has the advantages of high sensitivity, precision, light and small size. Besides, the radiation intensity of target is less affected by complex meteorological environment without cloud and mist above 20km. As the development of the attack and defense technology, infrared imaging detection technology is one of the main technologies in the strategic attack and defense technology represented by the long-distance fleetly accurately strike. When flight vehicles with infrared imaging systems fly at high speed in the atmosphere, the complex flow field formed between the optical dome and the incoming flow, causes interference of aerodynamic heat, thermal radiation and image transmission to the optical imaging detection system. It not only affects the strength and stiffness of the material, but also seriously reduces the detection ability and precision^[1] . This paper puts forward an analysis method of the detection ability of Infrared Imaging System in high thermal environment, and simulates the influence of effect factors on the detection ability. It provides reference to increasing detection distance of infrared Imaging System in high thermal environment.
