ABSTRACT:
This paper presents statistical signal processing approaches for
clutter reduction in Stepped-Frequency Ground Penetrating Radar
(SF-GPR) data. In particular, we suggest clutter/signal separation
techniques based on principal and independent component analysis
(PCA/ICA). The approaches are successfully evaluated and compared
on real SF-GPR time-series. Field-test data are acquired using a
monostatic S-band rectangular waveguide antenna.
