AWE应用于介质柱宽带RCS频率响应的快速计算
A Fast Frequency Sweeping Method for RCS of Dielectric Cylinders Computation Based on AWE Technique
摘要
Abstract
The method of moments (MOM) in conjunction with the asymptoticwaveform evaluation (AWE) technique is applied to predict the radar cross section (RCS) of an arbitrarily shaped two-dimensional (2-D) dielectric cylinder over a frequency band. The electric field integral equation (EFIE) of a 2-D cylinder is solved using MOM to obtain the polarization current on the cylinder. In the AWE technique, the polarization current at a given frequency is expanded in the desired frequency band in a Taylor’s series. The Taylor’s series coefficients are then matched via the Pade approximation to a rational function. Using the rational function, the polarization current is obtained at any frequency within the frequency range, which is in turn used to calculate RCS of the 2-D cylinder. It is observed that AWE can result in considerable CPU time saving.关键词
