Abstract
Ground penetrating radar (GPR) is a nondestructive measurement technique, which uses electromagnetic waves to locate targets or interfaces buried within a visually opaque substance or Earth material. GPR is also termed ground probing, surface penetrating (SPR), or subsurface radar. A GPR transmits a regular sequence of low-power packets of electromagnetic energy into the material or ground, and receives and detects the weak reflected signal from the buried target. The buried target can be a conductor, a dielectric, or combinations of both. There are now a number of commercially available equipments, and the technique is gradually developing in scope and capability. GPR has also been used successfully to provide forensic information in the course of criminal investigations, detect buried mines, survey roads, detect utilities, measure geophysical strata, and in other applications. Keywords: ground penetrating radar; ground probing radar; surface penetrating radar; subsurface radar; electromagnetic waves

A Compressive Sensing Data Acquisition and Imaging Method for Stepped Frequency GPRs

TL;DR: A novel data acquisition and imaging method is presented for stepped-frequency continuous-wave ground penetrating radars (SFCW GPRs) and it is shown that if the target space is sparse, it is enough to make measurements at only a small number of random frequencies to construct an image of thetarget space by solving a convex optimization problem which enforces sparsity through lscr 1 minimization.
