摘　　要：提出了一种适于工程应用的末制导DBS图像匹配方法,采用DBS成像,结合目标场景中强散射点的空间位置关系实现基于模板的目标场景匹配,快速定位及打击目标,较好地解决了末制导成像识别及定位问题。实测数据仿真结果表明,基于模板的DBS图像匹配算法可抑制多种图像畸变,具有较高的匹配可靠性和匹配精度,满足了雷达导引头DBS图像识别的工程使用要求,具有较强的实用价值。A practical technology of imaging and recognition for end-guided DBS Images matching is presented.Targets matching and orientation is realized by using DBS images and the geometrical position of strong scattering points.Experiments verify that this method is of lower operation and higher precision;meanwhile it is effective and robust when to resolve multi-aberrance of the matching images.In addition of that,it is a satisfaction to DBS image recognition of radar seeker,and also has more important project reference value.
