1. A method for determining the thickness of material by penetrating the material, in particular a method for measuring the thickness of walls, ceilings and floors, with which a measurement signal (28) in the gigahertz frequency range emitted using a single high-frequency transmitter (24) penetrates the material (10) to be investigated at least once and is detected by a single high-frequency receiver (38),wherein the thickness (d) of the material (10) is measured via at least two transit-time measurements of the measurement signal performed for various positions (20, 22) of the single high-frequency transmitter (24) and the single high-frequency receiver (34) operated in a same hand-held device.
