【Abstract】 The quality of infrared seeker in an optics system is quite essential to its detecting capability. We can exam seeker’s quality by using the test system that simulates practical situation. This article introduces our research method of such test system through the aspects of image manipulation and auto focusing, including the characteristics of facula image manipulation, the principle of traditional focusing control theory, and the selecting of the focusing functions, etc. In the end, we give out the simulating result and the error analyse. It has been proved that the detecting ability of this test system with infrared seeker attained the expected target and is promising for future practical use.更多还原
