Abstract

RWG based method of moment (MOM) is invalid in calculating the radar cross section (RCS) of large-scale chaff cloud. It causes unimaginable computational burden. This paper studies in detail the principle and solution process of the method of moments using pulse basis function and obtains the RCS of chaff cloud in a relatively short time. Compared with the MoM with RWG basis function, the proposed method greatly reduces the number of unknowns and thus improves the computational efficiency.
