Abstract
A 2D regularized pseudoinverse algorithm is described for subsurface imaging from multifrequency multi-monostatic ground penetrating radar (GPR) data. The algorithm is based on the Born approximation for vector electromagnetic scattering. Versions of the algorithm using both the ideal point sources/receivers, like the usual inversion algorithms of diffraction tomography (DT), and the arbitrary transmitting/receiving antennas based on Kerns' scattering matrix formulation are given. The algorithm allows either a lossless background medium or an attenuating background. The reconstruction results are obtained analytically by using a regularized pseudoinverse operator. The test results form both synthetic and experimental data are presented to illustrate the use of the algorithm.
