| 摘 要： | 目标的微运动所产生的微多普勒特征包含了目标的运动和结构信息.针对目标微运动特征的复杂性和差异性,以无旋翼目标和有旋翼目标为背景,分别建立了具有平动、加速与振动特征的散射点模型和具有平动、加速、振动及旋转运动特征的散射点模型,分析了两种模型的微多普勒特征及其差异.通过仿真,采用平滑伪Winger-Ville时频分析方法,从雷达回波中提取了两种复合运动的微多普勒特征,结果与理论推导一致,从而验证了模型及其微多普勒理论分析的正确性.

| Abstract: | Micro-Doppler signature produced by micro-motion contains movement and structure information which is useful for radar classification and recognition.Because of the complexity and difference of micro-motion,based on non-rotor targets and rotary-wing targets,the complex motion scattering point with translation,acceleration and vibration is modeled,so is complex motion scattering point with translation,vibration,acceleration and rotation.Then their micro-Doppler modulation and difference are analyzed.By simul... |
