The interaction of a radially polarized partially coherent beam with an arbitrary rough target embedded in a bi-static LIDAR system in the presence of atmospheric turbulence was illustrated. The target could modelled as a combination of a Goodman-like thin random phase screen and a Gaussian lens. Within the framework of paraxial approximation, the analytical formulas for the cross-spectral density matrix elements of the beam at the source plane, at the target plane, just after the target and at the receiver plane were derived. It was found that the statistical properties of the return wave were dependent not only upon the transverse correlation width of the target, but also on the turbulence. In addition, it was possible to predict the target type by measuring the spectrum and polarization properties of the return beam in the receiver plane.

说明了在存在大气湍流的情况下，径向偏振的部分相干光束与嵌入双静态激光雷达系统中的任意粗糙目标的相互作用。可以将目标建模为类似Goodman的薄随机相位屏幕和高斯透镜的组合。在近轴近似的框架内，推导了光束在源平面，目标平面，紧接在目标平面和接收器平面之后的交叉光谱密度矩阵元素的解析公式。发现返回波的统计特性不仅取决于目标的横向相关宽度，而且还取决于湍流。另外，可以通过测量接收器平面中返回光束的光谱和偏振特性来预测目标类型。
