Ground-Penetrating Radar Amplitude Analysis For Archaeological Applications

The primary goal of most GPR surveys is to identify the size, shape, depth and<br>location of buried remains and related stratigraphy. The most straightforward way to<br>accomplish this is by identifying and correlating important reflections within twodimensional<br>reflection profiles. These reflections can often be correlated from profile to<br>profile throughout a grid, which can be very time consuming. Another more sophisticated<br>type of GPR data manipulation is amplitude slice-map analysis that creates maps of<br>reflected wave amplitude differences within a grid. The result can be a series of maps that<br>illustrate the three-dimensional location of reflection anomalies derived from a computer<br>analysis of the two-dimensional profiles. This method of data processing can only be<br>accomplished with a computer using GPR data that are stored digitally.
