Dynamic infrared scene simulation study based on DMD imaging system

Dynamic infrared scene generator is one-of the important means to test the detection, track and anti-interference performance of the infrared seeker. The article to a certain type of air-to-air missile seeker loop simulation application object, based on the micro-mirror array (DMD), Vega Prime software and its infrared module for the development of tools,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.
