Description

technical field [0001] The invention relates to a real target scene simulation system based on a visible light target simulator, which can simulate and simulate the space environment and space targets, and can output dynamically, belonging to the technical field of target characteristics and detection. Background technique [0002] At present, the space target simulation is mainly based on the space target image simulation displayed on the screen, or using a computer to input a two-dimensional image and using an optical collimated projection system to output. [0003] Using the principle of film projection, a system for generating simulated images of space objects is composed of a computer image generation system, a film image source system, an optical coupling system, a main control computer, a control system and a two-axis turntable. This method uses the analog signal as the image input, limited by the image information provided by the film, which cannot be dynamically out...
