Abstract :
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.
