Abstract
This paper presents our global approach to model ultra-wideband (UWB) clutter. In this approach, we consider plane wave scattering (in the time domain) from a rough air-soil interface. The time-domain scattering is computed via two different techniques. The first one is a two-dimensional (2D) finite difference time domain (FDTD) algorithm, which is particularly well adapted to frequency-dependent subsoils. The second method is processed in the frequency domain prior to a discrete Fourier transform (DFT) which is performed to come back to the time domain. With this last method, we can integrate system parameters and statistically rough surfaces into our model.
