摘要

本文研究了利用pmchwt公式对天线罩封闭散射体进行RCS分析的精度。基于表面积分方程的分析方法被称为pmchwt -公式简要概述。结果表明，介质涂层导电球的散射截面图与精确解一致。然后将亚克力半球覆盖导电盘的RCS图与测量结果进行了比较。给出了椭球形天线罩封闭散射体的计算RCS图。我们验证了使用pmchwt公式的矩量方法对于雷达罩封闭散射体的RCS分析是足够准确的。

Numerical calculation and experimental validation of RCS analysis for radome-enclosed scatterer by using PMCHWT-formulation

This paper investigates the accuracy of RCS analysis for radome-enclosed scatterer by using the PMCHWT-formulation. The analysis method based on a surface integral equation known as the PMCHWT-formulation is outlined shortly. We show that calculated scattering cross section patterns of a dielectric coated conducting sphere agree with exact solutions. Then a RCS pattern of an acrylic hemisphere covered conducting disk is compared with measurement result. Calculated RCS patterns of ellipsoidal radome-enclosed scatterer are also presented. We verify the method of moments using the PMCHWT-formulation is sufficiently accurate for RCS analysis of radome-enclosed scatterer.
