This project conducted a systematic analysis of two sites. Both sites were constructed with buried features to simulate most archaeological sites (i.e. features were buried 1 meter or less in ground), and included various materials (metal, wood, etc.):

-The SERL test facility (CATS) is located on the University of Illinois campus. The soil at this site is high in clay and moist or wet most of the year. Data were collected in normal wet conditions, during a dry period, and when the ground was frozen.

-The Hanford Test Site (Hammer) is located in central Washington. This site is in a dry area, and its soils are primarily sand and silt. Data were collected in normal dry conditions, and when the ground was flooded by a sprinkler to simulate heavy rain conditions.

Along with the different soils and "weather" conditions of each site, data were collected with different antenna frequencies (ranging from 300 MHz to 900 MHz), various transect separations, and various acquisition parameters.

Using the data collected from these surveys, along with the known stratigraphy at each site we also:

-Made a detailed stratigraphic analysis to compare the known stratigraphy of each site to each unit (geological or archaeological) reflected on GPR profiles.

-Produced computer-generated modeling of the two-dimensional profiles created from the known stratigraphy, to show what GPR profiles "should" look like. These were compared to the profiles collected in the field in order to determine what certain objects "should" look like.
