ABSTRACT:
A method for measuring the fill level of a medium in a container by applying the radar principle, whereby a measuring signal is generated and transmitted in the direction of the medium. A retroreflected portion of the measuring signal is captured and the fill level is determined as a function of the runtime of the measuring signal. The measuring signal is transmitted into multiple mutually different regions and the retroreflected portions of the measuring signal is received at multiple receiving points. In this fashion, it is possible to at least approximate the surface structure of the medium in the container.
