摘　　要：为检验导引头的捕获、跟踪性能研制了一个三维场景模拟系统,它克服了野外实验的种种弊端。重点载入外部的导引头航迹和姿态数据,通过建立相应的数学模型实时模拟导引头运动引起的场景变化。同时,利用双缓存技术以及精确定时器的选用等实现系统实时性,并通过帧速率法得到了检验。与其他模拟系统相比,本系统具有2个特色:场景的模拟是由导引头数据驱动的;此模拟是实时的。实验结果证明本系统可以很好的满足实际的需要。In order to check up the missile seeker , a 3D scene simulation system is developed. The limitation of the out test is surmounted. Especially, by downloading the track and gesture data and basing relevant model, it drives the scene to simulate the change of the scene caused by the missile guide in real time. At the same time, it analyses what is real time in this system and how to carry it out by the technology of double buffer and high smart timer, as well as the frame speed is given to check up the real time. Comparing with other systems, this system has two aspects. One is the simulation of the scene is drived by the data and the other is it has very high demands on real time. By the results of experiment, the system can satisfy us very well.
