摘要：

动态红外场景生成系统是检测红外导引头探测、跟踪和抗干扰性能的重要手段。以某型空空导弹光电对抗平台为应用对象,基于红外场景实测数据,利用Visual C++6.0和Vega API开发了交互式红外图像生成软件,实时生成不同地域各种环境下目标和背景的红外图像,模拟真实场景在红外导引头入瞳处红外辐射分布。根据红外图像视频信号,利用数字微镜阵列(Digital Micro Mirror Device,DMD)对黑体红外辐射进行反射调制,并由光学准直系统实现红外场景生成系统与红外导引头的光学耦合,对红外导引头性能指标进行测试和评估。

Abstract:

Dynamic infrared scene generator is one of the important means to test the detection,track and anti-interference performance of the infrared seeker.Taking the development of the electro-optical countermeasures platform of some air-to-air missile for example,infrared images generation software is developed on the basis of Visual C++6.0 and Vega API by using measure data.Real-time infrared images with vary objects and backgrounds in different conditions are generated to simulate the infrared radiation at the pupil of the guide system.The radiation of blackbody is reflected and modulated by digital micro mirror device based on infrared video signal,which is used to test and evaluate the performance of infrared seeker.The results indicate that the system has the advantages of compact structure,high real-time performance,high frame frequency,high resolution,and great dynamic range.

Key words: infrared scene;digital micro mirror device;real-time
