【Abstract】 Under the hardware-in-the-loop requirements for the advanced multi-spectral optical and infrared imaging guidance weapon system,the methods to construct a multi-spectral and multi-target complex scene simulation system were discussed.The simulation system included multi-spectral projection and wide line-of-sight angle display system.Common aperture design method of multi-spectral projection was studied.A reflective coupling optical system was used to receive the multi-spectral scenes generated from visible projection,near-infrared projection,mid-infrared projection and far-infrared projection system,and then input the scenes into the wide line-of-sight angle display system to simulate the large angle of line-of-sight.Optical design for the whole multi-spectral projection was completed.The optical design results show that the approaches used in this paper are feasible and the aberration is acceptable.The design of this optical system which is multi-spectral,multi-target,wide field of view,long exit pupil relief and large exit pupil diameter,can provide basis for the build of complex EO countermeasure environment hardware-in-the-loop simulation facilities.更多还原
