In many practical applications, it is desirable to analyze the radar scattering from an object over a wide frequency band. Earlier attempts to achieving a fast frequency sweep involved the computation of higher order moments of the MoM matrix, which requires considerable fill time for each frequency point when the number of unknowns is large. In this paper, we present an approach for constructing a set of universal basis functions that can be used over the entire frequency band of interest. The use of this universal basis set obviates the need to factorize the block sub-matrices at each frequency, and results in considerable time saving. The numerical accuracy and the computational advantage of the proposed technique are illustrated by studying the problem of plane wave scattering from a PEC plate over a wide frequency band.
