Abstract
The present invention relates to a radar level gauge for determining a distance (D) to a surface of a product in a tank, said radar level gauge comprising: a transceiver configured to transmit an electromagnetic transmit signal (S) with varying frequency towards said surface and to receive an electromagnetic return signal (S), via a signal propagation device; a mixer adapted to mix the transmitted electromagnetic transmit signal with the received electromagnetic return signal to provide a mixer output signal including information about the surface's echo and information about another echo; and processing circuitry configured to apply an algorithm to the mixer output signal, which algorithm provides a distance-level rate matrix wherein the surface's echo and said another echo each is determined in the two dimensions distance and level rate, and to determine the distance to the surface based on the thus determined echo of the surface.
