中文摘要：
提出了一个新的转动圆柱和圆锥的激光距离多普勒像分析模型.该模型能分析圆柱和圆锥的几何参量、表面材料、姿态和脉冲宽度对这两种目标的距离多普勒像的影响,并能退化到平面波下的圆柱和圆锥的多普勒谱分析模型.数值分析了几何参量、表面材料、姿态和脉冲宽度对距离多普勒像的影响.理论和测量相结合,这个分析模型能用来进行圆柱和圆锥参量的识别.这个分析模型的解析表达式对于多普勒速度计和激光雷达应用有着重要的意义.
英文摘要：
We propose a new analytical model of range-Doppler image of cylinders and cones rotating around their axes. This analytical model can manifest the contribution of geometric parameters, roughness of the surface, and attitude as well as pulse duration to range-Doppler image. This analytical model degenerates into the analytical model of Doppler spectra for plane waves. The influence of geometric parameters, roughness of the surface, and attitude as well as pulse duration are analyzed numerically by applying the analytical model. Combining the theory and measurements, the analytical model can be used for parameter identification of cylinders and cones. This analytical solution may contribute to laser Doppler velocimetry and ladar applications.
