基于混沌特征的高分辨雷达目标识别

A Practical Method of Target Recognition based on Chaotic Feature for High-resolution Radar

根据高分辨导弹制导雷达的基本工作原则和舰船目标的散射特性,利用现有雷达回波的仿真技术,在合理的战术想定下,计算了三类典型舰船的雷达回波。在此基础上,研究了利用雷达回波功率谱的方法来识别目标类型的有效性,并基于混沌理论提出了一种比功率谱方法更加有效的新的识别方法,从而为进一步利用混沌理论来开发雷达目标识别技术奠定了初步的理论基础。

Using an existing method of simulating radar scatters and according to a reasonable tactical scenario, the radar scatters of three kinds of typical ships are calculated. Subsequently, the efficiency of radar target recognition using power spectrums of the data is studied and a novel chaos-based algorithm that proves more highly effective is presented. Our work lays foundations of further developing the radar recognition techniques using chaos theory.
