以未来导弹防御系统中先进体制成像雷达的识别手段为研究目标,针对目前主流的雷达目标识别技术,通过理论分析和电磁场仿真计算,分析了弹道导弹中段弹头目标的多种特征。结果表明,通过电磁场仿真计算可以很好地反映弹头目标的RCS特征、高分辨率一维像特征( HRRP)、ISAR二维图像特征和微多普勒特征,弥补了大多数弹头目标不能通过全尺寸暗室测量获取电磁特征的局限性。分析结果有助于支撑弹道导弹目标识别技术的研究。

Aiming to the target recognition methods of advanced imaging radar in ballistic missile defense system, the features of midcourse ballistic missile including RCS, HRRP, ISAR 2D im-ages and micro-Doppler features are investigated based on theoretical analysis and electromag-netic field numerical simulations. The research results show that electromagnetic field simula-tions can well consistency with the anechoic chamber measured data. The shortcoming is over-come that anechoic chamber cannot measure for most missiles. The simulation results are useful to understand the research of target recognition technique in ballistic missile defense systems.
