Abstract:A fast solution for electromagnetic scattering problems over a wide incident angle based on compressed sensing (CS) was proposed in recent years. Since current expansion coefficients are not known in advance, the parameters of this solution (e.g., the times of measurements, the selection of sparse transforms) for different scattering objects are difficult to determine. In order to solve this problem, this paper presents a prior parameter extraction method based on the principle of on-surface discretized bounda… Show more
