Abstract

SUMMARYThe goal of this paper is to develop an efficient and accurate computation scheme based on mixed‐order curved moment method for computing scattering from complex targets. To this end, the numerical performances of different kinds of higher‐order basis functions are presented and compared numerically. The formulae in the improved Duffy method for higher‐order curved moment method are derived and given explicitly. An efficient and accurate computation scheme is presented and implemented on the basis of the optimized triangular hierarchical higher‐order basis function and the improved Duffy method. Numerical experiments are performed to show accuracy and efficiency of the presented computation scheme for complex targets. Copyright © 2012 John Wiley & Sons, Ltd.
