Abstract

© 2016 SPIE. This paper investigates the use of the apex-shifted hyperbolic Radon transform to improve detection of buried unexploded ordinances with ground penetrating radar (GPR). The forward transform, motivated by physical signatures generated by targets, is defined and implemented. The adjoint of the transform is derived and implemented as well. The transform and its adjoint are used to filter out responses that do not exhibit the hyperbolic structure characteristic of GPR target responses. The effectiveness of filtering off clutter via this hyperbolic Radon transform filtering procedure is demonstrated qualitatively on several examples of GPR B-scan imagery from a government-provided dataset collected at an outdoor testing site. Furthermore, a quantitative assessment of the utility within a detection algorithm is given in terms of improved ROC curve performance on the same dataset.
