地面目标红外成像仿真系统的设计与实现

Design and Realization of Ground Objects Infrared Scene Simulator

设计了融参数化模型输入、数据及图像仿真、结果处理与评价、成像显示与存储于一体,汇计算目标流场、温度场、红外辐射特性等结果为一体的地面目标红外成像仿真系统;利用该系统开展了车载发电机组舱红外特性仿真,并将仿真计算与试验测试结果进行了比对,结果表明仿真方法合理有效,地面目标红外成像仿真系统可应用于类似目标、不同工况、多种背景下的地面军事目标红外成像仿真分析。

The Ground Objects Infrared Scene Simulator （GOIRSS） with calculated flow field, temperature field and infrared radiation signature function was designed. It was able to achieve parameter model importing, data and image simulating, results processing and evaluating, imaging displaying and storing. A vehicular generator cabin was used in infrared scene simulation by the Ground Objects Infrared Scene Simulator. The result of experiment and simulation data contrast showed that the simulator has advantages in effective modeling and is suitable for analysis on similar objects, different situation and multi-background.
