Ground Penetrating Radar |
|
| Ground-penetrating radar is a geophysical technique that sends electromagnetic pulses into the ground and records the pattern of their reflection. A radar antenna is towed along the ground surface and radar waves are sent into the ground. As they reflect off any archaeological buried features some of the waves are reflected back to the surface and are measured by another receiving antenna. The radar travel times are measured and stored on a computer. The readings can then be plotted to create a three dimensional picture of the features below the ground. See also geophysical survey. |
