Simulation of TRT-configured ground-penetrating radars over heterogeneous grounds

The transmitter-receiver-transmitter (TRT) configuration of the ground-penetrating radar (GPR) is a powerful tool to degrade the large undesired signals that dominate the total-received signal. Ground inhomogeneities, especially the ones in the surface of the ground, influence the measurements. However, the signals scattered from the target are still observed at the receiver.
