Paper Abstract

New ground penetrating radars for the vehicle mounted system can penetrate further into the ground, providing the opportunity of detecting objects that are deeply buried. A deep target has less obvious edge behaviors, especially if it has low-metal or non-metal content, making the edge based algorithm less effective for the detection. We shall explore the use of multiresolution time-frequency analysis technique by the log-Gabor filters to improve the detection of deep targets. They act on the 2-D image at an alarm location, generate multiresolution outputs and produce classification features for detection. The multiresolution analysis is able to preserve the edge behavior while at the same time forms the extra dimension of resolution (frequency) to better characterize a target signature for distinction with false alarms. Results on the detection performance at two government test sites validate the encouraging performance of the proposed detector.
