Radar is a system that uses electromagnetic waves to identify the range, altitude,
direction, or speed of both moving and fixed objects such as aircraft, ships, motor vehicles,
weather formations, and terrain. The term RADAR was coined in 1941 as an acronym for
radio detection and ranging. The term has since entered the English language as a standard
word, radar, losing the capitalization. Radar was originally called RDF (Radio Direction
Finder) in the United Kingdom. A radar system has a transmitter that emits either microwaves
or radio waves that are reflected by the target and detected by a receiver, typically
in the same location as the transmitter. Although the signal returned is usually very
weak, the signal can be amplified. This enables radar to detect objects at ranges where
other emissions, such as sound or visible light, would be too weak to detect. Radar is
used in many contexts including meteorological detection of precipitation, measuring
ocean surface waves, air traffic control, police detection of speeding traffic, and by
the military. - Wikipedia

Performs indoor and outdoor ground
penetrating radar imaging tailored to the specific needs of our clients. Our service
allows our clients to know the exact location of structural members such as rebar, conduit,
or post tension cables buried within the slab. By using the Radar system, the need for
expensive and dangerous X-Ray or blindly cutting into the concrete can be eliminated
in many cases. This technique can also locate voids in the concrete and assist in structural
analysis. See their Squidoo page.
