    摘要： The invention relates to a method for determining the fill level of a track-bound logistics installation providing intermediate storage for self-powered or externally powered vehicles, in particular in the form of a switching or shunting yard having railway cars arranged along a track installation, wherein, by means of radar technology, the vehicles are detected along at least one track of the logistics installation which is to be monitored, and the fill level is determined, that is, at least a number of vehicles along the at least one track to be monitored is determined, and represented. The method is characterized according to the solution by the combination of the following method steps: arranging at least one radar unit having a transmission and reception lobe region at a vertical distance (a) above the at least one track such that the at least one track to be monitored is located within the transmission and reception lobe region of the at least one radar unit; emitting radar waves and receiving radar waves reflected along the at least one track to be monitored in order to obtain a time series of radar signal data records, which contain the respective image information of the at least one track to be monitored at respective different times; processing the radar signal data records in order to obtain a time series of 2-dimensional radar signature images; carrying out a change analysis comparing at least two radar signature images selected from the times series in order to obtain a radar signature difference image; localizing and classifying vehicles at least on the basis of the radar signature difference image; and converting the localized and classified vehicles into a schematic diagram representing the logistics installation.
