Characterization and removal of unwanted artifacts in ground penetrating radar (GPR) imagery is a non-trivial task. The many factors affecting the presence, magnitude, and duration of such artifacts include their origin (man-made or naturally occurring), location (above ground or in-ground), dielectric constant, and moisture content, to name a few. It is of significant benefit to anomaly detection systems to remove such artifacts to reduce false alarm rates and increase threat alarm confidences. Man-made artifacts are typically a result of secondary reflections from the radar emitting surface and its related hardware. These "self-signatures" are manifested as artifacts below the ground surface that tend to be visible for all scans. However, when the sensor height is not held constant above the ground, the position (in time) and magnitude of the reflections become variable and difficult to predict. Naturally occurring artifacts include ground layers, sub-surface water layers, etc.
