To do this, we tested different GPR systems, antenna frequencies, and collection parameters on two artificially constructed sites. We collected radar data at these sites when ground conditions were wet, dry, and when possible, frozen.
In general, we found that:
*Certain features could be mapped while dry, while others could only be mapped while wet.
*Water is THE dominant factor affecting radar energy.
*Small transect spacing and middle to higher-range antenna frequencies are best for mapping archaeological sites.
