Wall-clutter mitigation using cross-beamforming in through-the-wall radar imaging
2010 18th European Signal Processing Conference, 2010•ieeexplore.ieee.org
A new technique for removal of the wall EM returns in Through-the-Wall Radar Imaging is
presented. It is based on the spatial notch-filtering to separate wall and target reflections.
The proposed technique forms squint beams at the receiver using a divided aperture. In
doing so, it removes the strong wall signature without eliminating those of the targets. The
proposed scheme provides desirable 3D target detection which is evaluated using real data
examples from Through-the-Wall radar imaging experiments.
