CLEAN Technique to Classify and Detect Objects in Subsurface Imaging

Abstract: An image domain CLEAN technique, for nondestructive and noncontacting subsurface imaging, is discussed. Recently introduced finite-difference time-domain- (FDTD-) based virtual tool, GrGPR, is used to create imaging scenarios and to generate synthetic scattering data through synthetic aperture (SAR) type scanning. Matlab-based imaging algorithms are used to process recorded FDTD data. The location and the geometry of the targets are obtained by image domain CLEAN technique which is extracting scattering center… Show more

“…A recently introduced GrGPR, virtual tool is used to generate synthetic data for sample scenarios [13][14][15]. In the simulations 50 transmitter/reciever antennas are placed over terrain and activated sequentially as in SAR principle or we can assume that a transmitter/reciever antenna pair is activated in 50 different positions over terrain (Fig.…”

“…A number of methods of signal processing have been put forward for improving landmine GPR system performance, including forward scattering radar classification [29], background subtraction, CLEAN algorithm [30], Kalman filters [31], likelihood ratio test [32], wavelet packet decomposition [33], and additional two-dimensional filtering [34]. The majority of these methods depends on estimating the background signal through Green's function or calculating a mean value for the unprocessed data collected by GPR and then subtracting the estimated background signal from the received signal.…”
