摘　　要：平均Hausdorff距离(MHD)方法基于编队的整体形状进行匹配来寻找对应点,因此,不像距离选择区法和扩展搜索图选择法那样受导弹自控段的导航误差和目标机动散布的影响。为了进一步提高反舰导弹的目标选择能力,考虑所匹配点集不同区域对Hausdorff距离函数的贡献程度不一样,提出了加权MHD(WMHD)来研究编队预定目标选择问题。首先通过刚体变换方法将火控雷达和末制导雷达探测到的编队点集进行位置匹配,然后利用WMHD方法获取其最优变换位置,最后据此最优变换位置预测预定选择目标在末制导雷达开机的位置。通过仿真实验表明其具有较强对抗冲淡干扰和形状扭曲失真的能力,且性能明显优于MHD方法。The Mean Hausdorff （MHD） method is based on the ship fomation to seach the corresponding point,so it is unlike the distance selection method and the extended search map selection method which are affected by the navigation error and the maneuver of the target distribution. To improve the anti-ship missile’s selection capability over the intended target of the ship formation, considering the match set of points’ different regions have different contribution to the Hausdorff distance function,it put forward the weighted MHD （ WMHD ）method to study the selection problem over the intended target.Firstly,this method takes advantage of the rigid transform to match the position of the point set which are respectively acquired by the fire control radar and terminal guidance radar. Then,the optimum transformation position is acquired by the WMHD method.Finally,the anticipation of the intended target’s position is acquired by the optimum transformation position at the moment of the terminal guidance radar’s start-up.The simulation experiments show that it possess the ability to against dilution jamming and shape distortion and its efficiency is better than MHD method.
