Simulation Method Research of Ground Target IR Scene Based on Aerospace Information

摘要

Infrared imaging guidance is a guidance system with strong anti-interference ability. It is a technology with high efficiency-cost ratio which increases the missile power. It also is one of precision guided munitions development directions nowadays. It is first step that studies on the infrared radiation characteristics of target region to study on infrared imaging guidance, in which the key is how to obtain the infrared information of target region. This paper presents a kind of target IR scene simulation methods based on aerospace information. Firstly, three-dimensional scene model is generated based on terrain data, target 3D data and remote sensing image data. Secondly, the value of target and scene surface temperature is computed with different methods. Finally, target region IR scene 24h image sequence is produced. After comparative analysis, the IR scene image sequence produced by this method reflects target region infrared radiation characteristics in truth, and has a good fidelity.
