Abstract

With the development of infrared technology, the cost of detector is decreasing and the application of staring imaging is becoming more and more extensive, which promotes the improvement of the antimissile warning level of the weapon platform. In the paper, a method for the antitank missile warning and precise recognition is presented based on the infrared characteristics of missile exhaust plume and the motion features of ballistic target. Firstly, the current status of missle warning technology is summarized. A hemispherical infrared staring detector of actual application is designed for ground weapon platform. The key technical indicators are given, and the technical routine of point target imaging warning is illustrated. Based on the above warning devices and typical observation scenarios, the relationship between target infrared radiation, observation distance and motion velocity is established, and a detection warning model is established. Combining with the actual application scene, the infrared warning distance window optimization, velocity calculation precision and point target recognition threshold are synthetically verified, and the analysis and quantification of critical data are gived. It showes that in typical scene detection and warning, the modeling of infrared characteristics and motion features can effectively achieve the antitank missile warning; under the control of observation conditions, the uncertainty of infrared radiation and motion velocity are less than 10%, which can be used to precise recognition the target under threshold of 30%.
