Measurement apparatus and measurement method for performing subterranean measurements

Abstract

A measurement apparatus (4) for performing subterranean measurements comprises at least one measuring structure (2) comprising at least one microwave sensor (102) for performing the subterranean measurements. The measuring structure (2) digs into the ground and moves inside a cut (600) of the soil (10) while said measurement apparatus (4) moves on the ground, and each of the at least one measuring structure (2) is configured to move in contact with the soil (10) within the cut (600). The at least one microwave sensor (102) measures at and / or below the ground level (12) on one or more sides of the cut (600) repeatedly when moving inside the cut (600).
