    摘要： Level measuring device which can compensate the distortions, caused by an STC filter, of the received signal, by measuring a reference signal which passes through the receiving branch and also through the STC filter, during the ongoing operation of the level measuring device or during manufacture. For example, after passing through the receiving branch, this reference signal can be fed to a microprocessor which can calculate the correction values of the IF signal therefrom. A switch can be provided which can switch over between the reference signal and the IF signal.

    摘要： For determining the topology of a bulk material surface, a series of echo curves are detected in different primary radiation directions of the antenna. Subsequently, for each distance cell of the echo curves, the maximum of all of the echo curves is determined and the distance thereof is plotted as a function of the coordinates thereof so as to obtain an image of the topology of the bulk material surface in two or three dimensions.
