Fast Calculation of Monostatic RCS by Calderón Multiplicative Preconditioner and Compressive Sensing
As scattering problems of subwavelength are analyzed over a wide incident angle,the trouble from ill conditioned impedance matrix and repeated computation would be a challenge topic.A novel method is proposed by Calderón Multiplicative Preconditioner(CMP)combined with a incident source based on Compressive Sensing(CS)to solve this problem.With help of Generalized orthogonal matching pursuit(GOMP),monostatic RCS can be fast and accurate constructed with less measurements.Numerical simulation results have shown that the computational efficiency of monostatic RCS can be further improved.
