Filling-level measuring device that evaluates echo signals

摘要

A filling-level measuring device, specifically a filling-level radar system, comprises a transmitter (1), a receiver (2) for an echo of a signal emitted by the transmitter (1), and an evaluation circuit (3) for estimating the filling level. The transmitter (1) and the receiver (2) are suitable for operation with a plurality of frequencies on the part of the emitted signal and the echo.
