摘　　要：为实现舰炮对岸上不可见目标精确打击,以使用无人机、侦察弹等观测手段为前提,提出采用基于图像匹配的末制导方式,通过对模板图像预处理与改进经典SIFT算法,达到图像快速匹配,准确末制导的目的。通过建模仿真验证了改进SIFT算法在遥感图像上应用的可行性,改进后的算法有效缩短了匹配时间,立足仿真数据,反向推导末制导开始前弹丸光学成像设备与目标的距离,建立开始匹配距离、匹配时间和末制导距离数学模型,通过具体数据分析,验证了图像匹配末制导应用于舰炮的可行性,为舰炮图像制导弹药研发构建了理论仿真框架。In order to realize the accurate attack of naval gun on invisible targets on the shore, a terminal guidance method based on image matching is proposed on the premise of using observation means such as unmanned aerial vehicle(UAV) and reconnaissance bomb. By preprocessing the template image and improving the classic SIFT algorithm, the goal of fast image matching and accurate terminal guidance is achieved. In this paper, the feasibility of applying improved SIFT algorithm to remote sensing images is verified by modeling and simulation. The improved algorithm effectively shortens the matching time. Based on the simulation data, the distance between the projectile optical imaging equipment and the target before the terminal guidance starts is reversely deduced, and the mathematical models of starting matching distance, matching time and terminal guidance distance are established. Through the analysis of specific data, the feasibility of applying image matching terminal guidance to naval gun is verified, and a theoretical simulation framework is built for the research and development of naval gun image guided ammunition.
