Abstract
The invention relates to a measuring system having a measuring array comprising a transmission and reception section and an electronic evaluation unit. In accordance with the invention, the distance between a first point and a second point is determined by moving the measuring array between the two points using the Doppler effect, with an intermediate frequency being formed in the transmission and reception section from the transmission frequency of the signal emitted by the transmission section and from the reception frequency of the signal reflected off a fixed object and picked up in the reception section, and the number of periods of intermediate frequency generated during the measuring operation being counted in the electronic evaluation unit to derive the distance.
