应用预处理AWE技术快速计算导体目标宽带RCS
Fast computation of wide-band RCS of PEC objects using preconditioned AWE technique
摘要
Abstract
When the Asymptotic Waveform Evaluation(AWE)technique is used in calculating the wide-band Radar Cross Sec-tion(RCS)of the object, the computational efficiency is improved greatly. However, the calculation of matrix inversion is very time-consuming when the objects are electrically large. Krylov subspace iterative methods are used to solve the matrix equation obtained from electric field integral equation instead of matrix inversion. The dual threshold incomplete LU factorization precon-ditioner is adopted to improve the convergence behavior of the Krylov subspace iterative methods. The numerical computation shows that the results are in good agreement with the results obtained by the method of moments at each frequency, and the com-putational efficiency is improved greatly.关键词
