Abstract

In this paper, the authors numerically analyze the scattering of electromagnetic waves from building walls by using the FVTD method. They consider three different types of rough surfaces such as periodic, random, and composite structures. They calculate the bistatic normalized radar cross section (NRCS) for horizontal and vertical polarization, and take account of the conventional optical reflection which corresponds to the n-th Bragg reflection for periodic structures. In addition, they investigate what conditions are needed in order to be able to ignore the higher order Bragg reflection for the periodic structures
