Abstract
The invention discloses a device for using radar signals to measure the vertical distance (h) to a surface, comprising a first transmitter and a first transmitting antenna for transmitting radar signals, and a first receiver and a first receiving antenna for receiving radar signals. The device additionally comprises a second receiving antenna and a second receiver, the second receiving antenna being arranged at a first predetermined horizontal distance (Δx) from the first receiving antenna, the device also being equipped with means for using signals which have been transmitted from the first transmitting antenna and received at the first and second receiving antennas to calculate the vertical distance to the surface. Suitably, the first and second receivers are one and the same physical unit, to which both the first and the second receiving antennas are coupled.
