Key Technology Research in Hardware-in-the-loop Simulation System of Strap Image Guidance Based on Virtual Scene

将捷联图像制导导引头实物和遥控中心引入仿真回路,利用虚拟场景,不仅为测试、改进导引头和目标识别与跟踪算法提供试验条件,更直观显示出弹丸的实时受控飞行弹道和相关数据。文中重点讨论了系统中的关键技术:虚拟场景生成系统、弹-目相对运动关键参数的计算以及系统实时性和子系统之间的协调同步问题等。该系统已成功应用于某型捷联图像制导导弹武器系统的半实物仿真试验中,取得了令人满意的效果。

Strap image guiding seeker and remote center are added to simulation loop. The virtual scene is not only for testing, improved seeker and target recognition and tracking algorithms to provide test conditions, but also gives more intuitive real-time display of controlled flight trajectory projectile and the related data. In this paper, the key technologies for realizing hardware-in-the- loop simulation system of strap image guidance based on virtual scene were discussed. It includes virtual scene generation systems, missile-target key parameters of relative motion computation, the system real-time coordination and synchronization between subsystems. The system has been successfully applied to hardware-in-the-loop simulation test of the strap image guiding weapon system, and achieves satisfactory results.
