NUMERICAL STUDY FOR LRCS OF COMPLEX OBJECT
-
摘要: 本文根据粗糙目标激光雷达散射截面(LRCS)的特点和工程建模方法,对复杂目标几何建模,消隐处理以及粗糙面特性研究的方法进行了分析和讨论.计算了飞机缩比模型在1.06m的后向LRCS,数值结果和实验有较好的吻合.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.
