摘要
本文根据粗糙表面的电磁散射理论计算了圆锥的后向激光雷达散射截面（ＬＲＣＳ）的非相干分量，分析了其随表面粗糙度的变化规律，并对非相干分量的概念进行了较为详细的阐述，希望能对外场全尺寸目标测量及实验室缩比模型的ＬＲＣＳ测量研究，提供一定的参考依据。
The incoherent baskscattering LRCS(laser radar cross-section) of cones with rough surfaces are calculated based on the electromagnetic scattering theory.Variation of LRCS with respect to roughness are analyzed,and a detailed interpretation of concept of incoherent LRCS is presented.The results show that the surface height variance will only result in a variation of LRCS'amplitude,while correlation length will have effects on both the amplitude and tendency of LRCS.
