一种快速计算目标宽带雷达截面的电磁算法
Fast computation of the wide-band radar cross section of arbitrary objects
摘要
Abstract
The adaptive integral method(AIM)combined with the best uniform approximation is applied to analyse the scattering of an arbitrarily shaped perfect electric conductor over a wide frequency band. It is lime-consuming to obtain the wide-band radar cross seciion(RCS)by repeating the calculation at each single frequency point. To solve the problem mor?efficiently, the Chebyshev nodes within a given frequency range are determined firstly, and the surface electric currents at those nodes are computed with AIM. According to the best uniform approximation, the electric currents can be obtained at any frequency within the given frequency range. Thus the wide-band RCS of the objects can be acquired. Dae to the fact that the AIM is employed to reduce matrix storage where full matrices are stored in a sparse form and to accelerate the matrix-vector multiplications, the algorithm reduces the solution time. Finally, numerical examples are presented to demonstrate the accuracy and efficiency of this technique.关键词
