Study of IR imaging target simulator based on zoom system

With the development of infrared counteraction technology, infrared imaging guidance has become the stream of photoelectric precision guidance technology. The situation of the hardware in the loop (HWIL) simulation for infrared imaging guidance weapon system is introduced. As for the HWIL simulation systems that are designed by the principle of one seeker to be simulated with one simulator, the new simulation scheme based on five-axis turntable is proposed. The HWIL simulation systems with zoom projection optical system can be used for the seekers that have different optical parameters, so the ratio of effect to cost is improved. Long wave zoom optical system that is diffraction limited is designed. The zoom ratio is 2.3, and the diameter of spot dispersion is no more than 50μm.
