How Ground Penetrating Radar Works
Ground Penetrating Radar (GPR) operates by emitting high-frequency electromagnetic pulses into the ground. These pulses penetrate different surfaces, and upon encountering objects or changes in material density, they bounce back to the receiver. The time taken for these signals to return provides data on the depth and location of subsurface features, aiding in creating detailed imaging.
Utilizing principles of electromagnetic wave propagation, GPR systems typically consist of a control unit, antenna, and monitoring equipment.
