Design of the machining, angle conversion, aiming control is difficult because tracking system in tracking guide simulation training is complex. For solving this problem, design a shooter tracking and aiming system based on rotary encoder and programming gate array chip. Analyze system composition, rotary encoder angle conversion and design principle, then put forward simulation result. The real application result show, the system can realize shooter tracking angle information output and aiming "cross line" motive control. The system has the characteristics of simple structure, low cost, convenient operation and is important on raising the shooter operation level.%为解决制导跟踪模拟仿真训练过程中实装跟踪机构复杂,导致机械加工、角度转换和瞄准控制设计难度较大的问题,设计一种由旋转编码器和可编程门阵列芯片组成的射手跟踪瞄准系统.分析系统组成、旋转编码器角度转换和设计的原理,并给出仿真结果.实际使用结果表明:该系统能实现射手的跟踪角度信息输出和瞄准"十字线"的移动控制,具有结果简单、成本低和操作方便等特点,对提高射手操作能力具有较为重要的意义.
