Method for the evaluation of radar data for fully automatic creation of a map of regions with interference
First Claim
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.

Abstract
A method for the evaluation of radar data for fully automatic creation of a map of regions with interference, in which undesirable reflections frequently occur includes the following method steps. The region to be mapped is divided up into cells. The short-lived target tracks that occur in these cells are counted. Statistics are kept, in such a manner that the short-lived target tracks are counted only within a predetermined period of time, while all older short-lived target tracks are left out of consideration. At least one threshold value is predetermined, in such a manner that a cell is considered to have been marked if the short-lived target tracks that are counted in the previous time period exceed the threshold value or values. The map of the current regions with interference results as the totality of the marked cells.
