Ground‐Penetrating Radar (GPR) data that are frequency filtered will produce a variety of data sets, each with a differing subsurface resolution. At the site of Petra, Jordan, filtered reflection data were processed to produce discrete categories of low (200–350 MHz), middle (500–650 MHz), and high (650–800 MHz) frequency wave amplitudes. The high frequency reflections were especially effective in identifying construction techniques from a buried Nabataean age wall. The results suggest that post‐acquisition GPR data frequency filtering may be helpful in identifying some differences in construction techniques and building materials in otherwise difficult to interpret subtle buried features.
