GPR uses pulses of high-frequency radio waves to image the subsurface. Our systems cover a wide range of frequencies, the choice of which will be determined by the required depth of penetration, target resolution and ground conditions.
The lowest frequency antenna we have is 25MHz, suitable for ice depth studies or similar deep soundings. The highest is 1GHz, with a typical penetration depth of only a few centimeters, and is suited to precise measurement of snow accumulation or similar. The intermediate frequencies of 50, 100, 200, 250 and 500MHz are the most widely used for many different geophysical investigations in ice, sand, soils and even fresh water.
