LASER BACKSCATTERING BY AN ARBITRARILY SHAPED DIELECTRIC OBJECT WITH ROUGH SURFACE
-
摘要: 本文研究具有粗糙表面凸形物体的光频后向散射。由几何光学基尔霍夫近似,获得相干后向散射截面和非相干后向散射截面理论计算公式。以粗糙球和粗糙椭球为例分析了物体几何参数,介电常数和粗糙表面统计参数对红外激光后向散射截面的影响。Abstract: The backscattering of light wave from arbitrary convex dielectric objects wich rough surface is investigated and the formulas for calculating the backscattering cross-section of both coherent and incoherent fields are obtained. In the infrared wave-band, the influence of the geometry, permittivity and statistic characteristics of the rough surface on LRCS is analysed, making use of rough spheres and ellipsoids as examples.
