Innovative ground-penetrating radar methods for archaeological mapping

The three-dimensional complexity of ground-penetrating radar (GPR) data can be one of its strengths, as multiple factors are included in "cubes" of radar wave reflections. These parameters are time that can be converted to depth, wide bands of wave frequency that are capable of differing feature resolution and wave amplitudes that are a function of material differences at buried interfaces. When GPR data are filtered and corrected to enhance aspects of these factors, many otherwise invisible buried features become visible in the resulting maps and images. This can allow for buried archaeological feature resolution even in the most cluttered and noisy urban environments, as demonstrated by GPR maps from Santa Fe, New Mexico.
