Advanced Ground Penetrating Radar Signal Processing Techniques

摘要

Ground penetrating radar (GPR) is a non-destructive geophysical method that uses electromagnetic waves to image the subsurface. A typical GPR system has three main components: transmitter and receiver, directly connected to the transmitting and receiving antennas, and a control unit. Electromagnetic pulses are transmitted into the subsurface and the earth response is recorded. The GPR method is characterized by the rapidly decaying amplitude of the electromagnetic waves, together with the loss of the relevant higher frequency harmonics. Thus, GPR data are highly non-stationary and processing is inherently a challenge.
