Abstract:
1. A device for determining a fill level and mobility of an echo, comprising: a processor determining a first position shift of a first echo of an echo curve during a defined time interval, the processor determining a second position shift of a second echo of the echo curve during the defined time interval, wherein the processor calculates a mobility value of the second echo of the echo curve by using the first position shift, wherein the mobility value of the second echo is a characteristic relating to the second position shift of the second echo and to the first position shift of the first echo, wherein, when the second position shift of the second echo is zero, the first position shift used for the calculation of the mobility value of the second echo of the echo curve always results in a decrease of the mobility value of the second echo of the echo curve, and wherein the mobility value is used to determine whether a track of the second echo is one of stationary and dynamic.
