The role of the measurement configuration in inverse scattering from buried objects under the Born approximation

In this paper, the inverse scattering problem for dielectric objects in a two-dimensional half-space geometry is dealt with. The discussion is worked out in the framework of the linear model of the Born Approximation (BA) and the role of the measurement configuration is investigated with regard to the information content of the scattered field data. In particular, the configurations analyzed are multiview-multistatic, multibistatic and multistatic with a single view, all exploiting a frequency diversity and with the observation line at the interface. The comparison shows that the multibistatic configuration seems to offer a good compromise between the required measurement time, the computational “burden” and the quality of the achievable results.
