| 摘 要： | 针对巡航导弹在作战过程中可能遇到的各种局部强干扰．本分析了局部强干扰对景象匹配的影响．提出了一种实用的抗局部强干扰的景象匹配算法——基于小窗口的升块匹配算法．即粗匹配阶段将实时图分块．采用AD算法将受强干扰区域滤除．精匹配阶段采用Nprod算法确定最终匹配位置。仿真试验证明．该算法能够满足匹配可靠性和实时性的要求．具有良好的应用前景。

| Abstract: | Considering various possible partial intensive interferences in the process of cruise missile's terminal guidance, this paper analyzes their effects on image matching, and proposes a practical image matching algorithm based on block partition by small windows. This algorithm partitions the real-time image into blocks, filters the area suffered by the intensive interference in rough matching, and fixes the final matching position through the Nprod algorithm. Simulation shows that this algorithm is able to satisfy the requirements of reliability and rapidity and has favorable application prospect. |
