Abstract : An accurate model representing scattering of radar signal due to inhomogeneous media is a valuable tool for ground penetrating radar (GPR) signal processing. The model should account for the antenna radiation pattern as well as effect of inhomogeneous media. In this work, a full wave model (FWM) is analytically solved to obtain a compact and closed form expression to represent bi-static GPR applied to a two-layered media. The model is validated by comparing its accuracy with well-known full wave models in the literature. Since, spectral domain integral formula is replaced by a simplified formula involving basic arithmetic operations, its computation speed is enhanced. The new model would be a valuable signal processing tool for analysis and detection of bi-static on-ground GPR configurations
