RCS Simulation of Corner Reflector Based on FEKO
摘要
基于 FEKO 平台的物理光学算法是模拟人工角反射器等电大尺寸目标的理想算法.根据物理光学算法模拟三角锥体角反射器的 RCS 曲线,与理论最大值结果进行比较,两者取得了较好一致性.RCS 曲线的分析结果可用于指导实际试验场的人工角反射器的合理布设,从而使角反射器在 SAR 影像上的幅度值最大化,提高 CR-In-SAR 的形变监测精度.
Abstract
FEKO is an advanced simulation tool which is applied to analyze 3D electromagnetic field.Physical optics is an important algorithm in FEKO
which can simulate electrical large-scale targets
such as artificial corner reflector.In paper
pyramid trihedral angles RCS curve is obtained with PO. The simulation result is good consistency with theoretical max value.Through analyzing RCS curve
it can help choose the right type of corner reflector and provide guidance on how to set up CR in the fields.When RCS of artificial corner reflector achieves maximum
it is easier to recognize CR from SAR and increase monitoring accuracy.
