Abstract

A hybrid algorithm that combines the finite-element time-domain (FETD) method and generalized scattering matrix (GSM) technique is proposed to efficiently compute the broadband monostatic radar cross-section (RCS) of a large and deep open cavity. The formulation and implementation for the numerical modal analysis of arbitrary cross-sections and the FETD method equipped with complex frequency shifted perfectly matched layers (CFS-PML) for transient simulations are presented. The broadband monostatic RCS is evaluated using a broadband GSM obtained by the FETD solutions. An electrically large example is presented to demonstrate the accuracy and efficiency of the proposed hybrid FETD-GSM algorithm for broadband monostatic RCS computation and inverse synthetic aperture radar (ISAR) imagery of large and deep open cavities.
