摘要: 本文根據(jù)粗糙目標(biāo)激光雷達(dá)散射截面(LRCS)的特點和工程建模方法,對復(fù)雜目標(biāo)幾何建模,消隱處理以及粗糙面特性研究的方法進(jìn)行了分析和討論.計算了飛機(jī)縮比模型在1.06m的后向LRCS,數(shù)值結(jié)果和實驗有較好的吻合.

Abstract: Based on the characters and engineering modeling of Laser Radar Cross Section(LRCS) for the object with rough surface, some methods of geometric modeling and hidden processing for complex object are analyzed and discussed in this paper. The angular distributions of backscatter-ing of laser radar cross section for airplane model are computed at 1.06m. The numerical results are in good agreement with experimental data. -
