基于Hausdorff距离的反舰导弹目标选择方法

A Target Selection Method for Anti-Ship Missile Based on Hausdorff Distance

摘要:

如何从舰艇编队中选择预定目标,是超视距反舰导弹亟待解决的一个问题。文章基于Hausdorff距离的部分匹配理论研究了这一问题。火控雷达探测到的编队信息和末制导雷达探测到的编队信息都用点集来描述,通过点集形状匹配获取这两个点集的对应点,从而实现对预定目标的选择。重点提出了一种新的部分匹配途径,能够自适应地逐个剔除引起形状不相似的外部点而同时保留两个形状的相似部分。仿真试验表明,相比以往基于编队相互位置关系的方法,论文所研究的预定目标选择方法具有更好的抗干扰能力。

Abstract:

It’s in dire need of a method to select the designated ship from a ship formation for over-horizon anti-ship missiles. This problem was studied by making use of shape matching based on Haudsorff distance. The data about the ship formation, acquired by fire control radar or terminal guidance radar, are described with two point sets respectively. The designated ship can be selected while the two point sets are matched with their correspondence by shape matching. A new partial matching approach based on Hausdorff distance was proposed, which automatic could remove the outliers which brought dissimilarity to two shapes, while keeping the similar parts of two point sets. Simulation experiments showed that the ability to confront interferences was better than the method using mutual position relationship (MPR).
