definition: The development of sounding techniques and radar imagery in the study of planet surfaces and subsurface has enabled us to explore the geophysical properties of many parts of our solar system, in particular Venus, Earth, the Moon, Mars and the Titan, as well as asteroids and comets. The new observations have brought about a fundamental change in our understanding of the geological and geophysical evolution of the various planetary environments. Sounding radars are able to explore these environments through the penetration of geological material with low-frequency electromagnetic waves. Penetration depth can be anything from a few centimeters to several kilometers, depending on the sounding frequency and the physical properties of the ground.
