针对某型全捷联电视导引头的末制导测试，在常规的半物理仿真系统中增加了可视化仿真系统和制导环节，搭建了基于典型目标打击的闭环仿真实验系统，为图像跟踪算法及导弹制导律的验证提供了一个平台；整个系统包括可视化仿真、导引头、制导系统、自动驾驶仪系统、弹体动力学、转台及 IMU，其中可视化仿真作为闭环的输入端，提供了导弹外场发射的场景，为导引头直接提供战场探测信息，导引头发送目标脱靶量信息至制导系统，通过自驾仪解算及舵机指令输出，经过弹体动力学更新弹体的姿态位置信息，驱动转台同时反馈至可视化仿真系统，实现末制导闭环仿真。最后，通过该型导引头进行了实例测试，仿真结果验证了可视化半物理仿真系统的正确性和有效性。

Based on the test of terminal guidance for a certain TV seeker,visual simulation system and guidance were added to the conventional semi-physical simulation system. A closed-loop simulation system based on the typical target strike scenario was built,which provides a test platform for the verification of image tracking algorithm and guidance law. The system consists of visual simulation,guidance seeker,au-topilot system,missile dynamics,three-axis revolving table and IMU. The visual simulation was the input of the closed-loop system,which provides scenario of the missile launch and provides observation informa-tion for the seeker. The seeker system then transmitted the miss distance to the guidance system. The serv-er commands were generated according to the calculation of autopilot. Next,the position and attitude of the missile were then updated based on the missile dynamics,which drive the platform and serve as the feed-back of visual simulation system. A close-loop simulation of terminal guidance was thus built up. Finally, the TV seeker was tested,and the simulation results show that the proposed semi-physical simulation sys-tem is correct and effective.
