Research on target infrared characteristic modeling technology in target system

针对自主对抗条件下红外靶标系统的需求,对适用于该领域的目标全向红外特性建模及校验技术进行研究。对某型靶机目标进行精细三维建模,将主要红外辐射源等效为红外光源,利用光学仿真软件通过有限光学追迹法,对各角度观察面处的红外辐射强度进行仿真,从而获得目标全向红外辐射模型。进行了地面实际测试,实验结果和仿真结果符合良好,验证了该建模仿真方法可行,可为相关领域研究提供理论支持。

A kind of omnidirectional infrared characteristic modeling and verification technology are proposed for target systems under independent against conditions,in this paper.By fine 3D modelling,equivalent the main IR source to light source,a target drone IR infrared characteristic are modeled by emulation the IR radiation intensity at the observation surface of all viewing angles through the finite optical tracing method in optical simulation software.The IR characteristics of the target drone are tested on the ground.The experimental results are in good agreement with the simulation results,which verifies that the feasibility of modeling and simulation method,and could provide theoretical support for related research.in future.
