Abstract

The Lincoln Laboratory ground-based rail SAR was used to collect UHF band data on buried and partially buried trihedral corner reflectors in Yuma soil. The frequency range was 0.25 to 1 GHz in discrete steps. Both HH and VV polarization data were collected in the vicinity of the pseudo-Brewster angle. The partially buried trihedrals revealed two principal components for the returned signals: (1) a surface reflected component, and (2) a ground penetrated component. A model is described for partially buried trihedrals that accounts for these two components and the model is used in estimating ground penetration parameters.
