The fidelity with which microgeometry features need to be represented in models of electrically large complex objects used for radar cross section (RCS) calculations, is an important consideration for which there currently is no clear guideline in open literature. In this paper the results presented in [5], related to the effects of microgeometry on RCS, are further investigated using high range resolution profiling. The results show several characteristics of the scattering contributions of microgeometry features of different electrical sizes.
