Abstract:
1. A method for evaluating radar data for fully automatic creation of a map of regions with interference in which undesirable reflections frequently occur comprising the following steps: (a) dividing a region to be mapped into a plurality of cells; (b) counting short-lived target tracks that occur in the cells; (c) maintaining statistics so that the short-lived target tracks are counted only within a predetermined period of time while leaving out of consideration all short-lived target tracks occurring prior to the predetermined period of time; and (d) setting at least one threshold value so that a cell within the plurality of cells is considered to have been marked if the short-lived target tracks that are counted in a previous time period exceeds the at least one threshold value; wherein a map of current regions with interference results from a totality of marked cells.
