Abstract
A method of determining a filling level of a product in a tank using a radar level gauge system comprising a transceiver, an antenna, and processing circuitry, the method comprising the steps of: generating and transmitting a transmit signal; receiving a reflection signal resulting from reflection of the transmit signal; determining based on the transmit signal and the reflection signal, for each surface echo candidate, a first measure indicative of a distance and a second measure indicating a rate-of-change distribution of the distance; assigning one surface echo candidate as most likely to correspond to single reflection of the transmit signal at the surface of the product, based on an evaluation of the second measure for each surface echo candidate; and determining the filling level based on the first measure for the assigned surface echo candidate.
