摘　　要：光学探测设备在载体飞行过程中对目标进行大范围的扫描凝视运动,由于目标范围大,探测器分辨率高、视场小,因此光学探测设备扫描频率很高,给半实物仿真造成了极大困难。传统弹目视线运动仿真常用的五轴转台由于自身动态性能的原因无法跟踪探测设备的光轴运动变化。针对上述情况提出了一种基于宏/微双重驱动的光学制导仿真视线运动模拟方法,利用五轴转台、目标模拟器、二维摆镜等仿真设备建立了一套光学制导半实物仿真系统,以实现弹目视线大范围、高动态、高精度仿真。实验结果表明,上述弹目视线仿真方法能够有效实现对弹目视线大范围、高速度切换的模拟,并提高了系统的仿真精度,使其达到指标要求。The optieal detection device scans the target in a large scale during the flight. The optical detection de- vice has a high scanning frequency because of the large target range and small field of view. The target simulator is installed on the two outer frame of the turntable, and the turntable can not track the optical axis movement speed of the detecting device because of its dynamic performance. So the paper presents a method of optical guidance simulation LOS motion based on macro/micro dual drive. A semi-physical simulation system of optical guidance was built by using five-axis turntable, target simulator and two-dimension waving mirror in order to realize large range, high dynamic, high accuracy of simulating the missile-to-target LOS motion. The experimented results show that the sinmlation method can effectively realize the simulation of large range and high speed switching of the missile-to-target LOS, and improve the simulation accuracy of the system to meet the requirements.
