为提高红外图像的仿真效果, 在Vega平台实现动态红外图像的仿真。首先分析了目标场景辐射特性模型、大气传输模型以及红外探测器模型, 然后以F-16飞机为例详细地分析了Creator建立三维模型和在Vega平台完成动态红外图像仿真的过程, 最后利用MFC和Vega API编程开发了友好的交互界面, 用于不同仿真条件的切换和参数的调整。仿真实验结果表明该方法简单易行、有较高的逼真度, 可为红外目标模拟器提供信号源。

In order to improve the effect of infrared imaging simulation we implemented dynamic infrared image simulation based on Vega.The target scene radiation model atmospheric transmission model and the infrared detector model were analyzed at first.Then the processes of Vega based dynamic infrared image simulation and Creator based 3D model construction were analyzed taking F-16 aircraft as an example.In the end a friendly interface was developed using MFC and the Vega API for switching between different simulation conditions and adjusting parameters.The result of the simulation shows that the algorithm proposed in this paper is simple in operation and has high fidelity which can supply signal source to the infrared target simulator.
