Research On Infrared Seeker In Hard Ware-in-the-loop Simulation System Of Laser Guidance Weapon

Hardware-in-the-loop simulation system of Laser guidance weapon can reduce the development time of semi-active laser-guided weapons and save cost. The simulation seeker is one of the important part of the hardware-in-the-loop simulation system, which determines the positioning accuracy of hardware-in-the-loop simulation system. In this paper, the infrared seeker is designed for Hardware-in-the-loop simulation system of Laser guidance weapon in the laboratory environment.Firstly, this thesis analyses the performance of infrared seeker Hardware-in-the-loop simulation system of Laser guidance weapon, on the basis of using ZEMAX software to design the optical system of infrared seeker, and verify the feasibility of the optical system design; Secondly, based on the detailed analysis of the four quadrant detector target localization method, the four quadrant detector processing circuit is designed and get the target location information. Finally, we can capture and track the target by combining the target simulator of hardware-in-the-loop simulation system and two axis turntable motion control in the laboratory environment.
