Ground Penetrating Radar (GPR) is based on the emission of electromagnetic waves into the ground and the detection of reflections from objects in the subsurface. From the measured travel-times, the location and depth of these objects can be determined. GPR is frequently used in the search for buried structures in the first few meters of the subsurface (pipes, archaeology, civil engineering). The depths of investigation depends on the antenna frequencies and the conductivity of the surveyed ground.

A classic sonar emits an acoustic signal towards the bottom of the water body and analyzes its echo. Knowing the propagation velocity of the acoustic waves in water and the time between emission and detection of the signal, it is possible to calculate the distance between the sonar system and the floor.
