摘要
针对末制导导引头对港口多个舰船目标识别、分选的技术难点,该文将距离高分辨技术与单脉冲测角体制相结合,提出了一种基于毫米波单脉冲三维成像的港口舰船目标识别、分选方法。首先采用单脉冲三维成像获得目标散射中心的三维分布,然后利用聚类分析等方法实现目标的分割与识别,并将无偏几何中心法用于目标跟踪点的选择,从而实现导引头对多个舰船的识别、分选及精确跟踪。仿真结果表明,文中方法对多个目标的识别及目标要害部位选择具有很大的优越性。
To solve the problems in identifying and selecting muhi-ships for terminal guidance radar seeker, an algorithm based on the millimeter monopulse 3D imaging is presented. Firstly the 3D imaging technology is used to gain the targets＇ scattering center distribution, then the algorithm uses clustering analysis methods to realize the division and recognition of targets, and the unbiased geometric centre tracking method is utilized to track the true and unbiased geometric centre of an array of scatters on a single target. Simulation result indicates that this method has obvious advantages in multi-targets distinguishing and selection of the vital parts of a target.
