| 摘 要： | 进动是锥体目标空间自旋飞行时特有的运动特性,通过刚体姿态动力学原理,采用微动分析方法分析了光滑表面锥体弹头目标的空间进动模型,并由雷达电磁散射原理建立了目标宽带回波模型.通过散射点仿真模型和电磁仿真数据,采用周期检验的方法分别对锥顶和锥尾散射点的进动参数进行提取,验证了分析和模型的正确性.

| Abstract: | Precession is the special feature when conical reentry target is in spatial motion with spin.The spatial precession model of conical reentry target is analyzed through the theory of rigid body dynamics and the method of micro motion.The wide-band echo model of spatial precession of cone reentry target,which has smooth surface,is obtained by the analysis of its electromagnetic scattering effect.Their coning periods are estimated by the method of period analysis based on their simulation data.So the validity ... |
