Multioffset ground penetrating radar (GPR) data provides numerous imaging benefits over common-offset GPR data, such as increased depth penetration, reduced noise, and improved structural imaging. However, the large dataset acquisition times often discourages its use. Rapid multioffset data acquisition acquires traces continuously as common source gathers, providing an average time savings of two to five times that of stationary multioffset surveying. Rapid multioffset data acquisition uses the existing bistatic GPR system, is cost-effective, and acquires a high fold, while maintaining signal quality and positioning accuracy. A time-dependent dewow correction increases depth penetration while preserving resolution in multi/common-offset data. The removal of wavelet dispersion from multi/common-offset data via inverse-Q filtering improves vertical resolution and interpretability. Rapid multioffset data is applied in the diverse archaeological contexts of Roman ruins and Native American sites, and should encourage the use of multioffset datasets more regularly.
