Analysis on angle polarization correlation of ballistic missile target

现代信息化战争条件下,随着相关技术的不断发展更新,弹道导弹中段目标的识别难度越来越大。近年来,极化特征在目标识别领域得到了广泛应用。本文首先采用建模仿真的方法获取了五类中段目标的动态全极化散射数据,然后在窄带和宽带两种雷达体制下分析了五类目标的角度极化相关性,仿真结果表明,角度极化相关性可用于目标的初识别;在此基础上,进一步研究了进动参数对目标极化相关性的影响,所得结论对目标的精细识别有一定的参考价值。

At present,the target recognition of midcourse ballistic missile is more and more difficult as a result of the continuous development of relevant technology.In recent years,the polarization characteristics have been widely ap-plied in the field of target recognition.Firstly,the dynamic full polarization scattering data of five kinds of midcourse targets is obtained through modeling and simulation.Then the angle polarization correlation of the targets is analyzed with the narrowband and broadband radar system.The simulation results show that angle polarization correlation can be used in the preliminary target recognition.On this basis,the impact of the precession parameters on target polariza-tion correlation is studied.And the conclusions have certain reference value for fine identification of the target.
