摘要

研究了散射电磁仿真中复杂形状物体面模型的建立问题。为了考虑物体某些部分之间的再反射，建议使用光线追踪和kd-tree方法。为了减少建模所需的时间，提出了一种简化物体几何模型的算法。对相同目标但面数不同的计算场进行比较，结果表明面组合在不影响精度的前提下加速了仿真。

Facet Model Processing for Complex Shape Object Scattering Calculation

The problem of construction a facet model of complex shape object for simulation of scattering electromagnetic is considered. It is proposed to use the approach of raytracing and kd-trees in order to take into account the re-reflections between some parts of the object. An algorithm for simplifying the geometric model of the object is proposed in order to reduce the time necessary for modeling. Comparison of calculated fields for identical objects, but with a different number of facets, showed that combining facets accelerates the simulation without violating its accuracy.
