GROUND PENETRATING RADAR (GPR) - MEANING, OPERATION, APPLICATIONS, COMPLICATIONS, AND LIMITATIONS
WHAT IS A GROUND PENETRATING RADAR (GPR)? Ground Penetrating Radar works on the geophysical locating
method,
which
uses
radio
frequencies
to
capture underground images. It is possible to perform concrete scanning with GPR without disturbing the surface layers of the ground.

The operational process of GPR devices can be divided
HOW DOES GROUND PENETRATING RADAR (GPR) WORK?
into three following stepsFirst, GPR emits weak radio frequencies GPS detects the echoes reflected and uses the same to create an image It displays signal time delay and strength 03/04
APPLICATIONS OF GPR There are plenty of use-case of GPR, such asFor construction Measuring underground water content Concrete coring Bedrock mapping Archaeology Defense Forensics

LIMITATIONS OF GPR GPR device is sensitive to noise. Unwanted geologic noise can cause unwanted reflections. GPR is a bulky and heavy device
