摘　　要：分析了特定目标的特点,提出了一种解决远处高速小目标高分辨率成像的方法。这里采用引导相机和成像相机相结合搭载在高精度二维转台的方案,解决目标搜索和粗略跟踪的问题。方案在成像相机中引入积分时间控制与利用高精度二维平动台实现像移补偿的精跟踪机制。另外,在后期采用运动模糊恢复处理来改善图像质量,解决运动补偿不完全可能引起的像模糊问题。文中给出了具体设计的参数要求和电子学解决方案,为具体实施提供基础。The paper proposes a new scheme to detect the small target crossing rapidly with high resolution.In the scheme,a leading-camera and an imaging-camera which are built in a high precision 2D wheel are employed to finish target searching and rough tracking.In the imaging-camera,both integration time controling and precise tracking mechanism are used.Further,the image processing will be taken on PC to remove the blur due to movement.The paper presents the requirements of system and its electronic solution,which can be the basis of engineering realization.
