摘要
设计的红外导引头主要为激光半主动制导半实物仿真系统的目标捕获装置,它的性能直接影响整个半实物仿真系统的定位精度。首先在详细分析了导引头的性能指标基础上设计一套红外导引头的光学系统,并用ZEMAX验证了光学系统设计的可行性;同时设计了四象限探测器的处理及采集电路,实现了目标方位信息的捕获;最后结合三轴运动转台的控制实现了目标的跟踪。本系统经实验验证能够在实验室环境下完成对激光目标模拟器的捕获和跟踪。
In this paper, infrared seeker is designed as a target acquisition device for laser semiactive guidance hard- ware-in-the-loop simulation system.Its performance directly influences positioning precision of the whole of hardware-in-the-loop simulation system.Firstly, this paper analyses the performance index of infrared seeker and designs a set of optical system, and the feasibility of optical system is verified by ZEMAX; Then, the processing and acquisition circuit of four quadrant detector is designed to capture the position of target; Finally, this system achieves target tracking by controlling three-axis turntable motion.Through the experiment, it＇s verified that this system can capture and track laser target simulator in the environment of laboratory.
