| description | The invention discloses a multi-satellite passive positioning scatter target classification method based on DTO separation, and relates to the technical field of satellite positioning, and the method comprises the steps: accumulating DTO data of a time slice, and carrying out the data preprocessing; clustering the target DTO under each double-satellite combination of each single positioning system to obtain a DTO grouping sequence; fusing the DTO packet sequences under the combination of the multi-positioning system and the double satellites to obtain a new DTO packet; and based on the new DTO grouping, clustering the target position points and removing mirror image points, and outputting a sequence of each target position point. The multi-target positioning scatter clustering method based on DTO separation is provided by using time difference distribution characteristics of different targets passing through satellites so as to support automatic target clustering of positioning scatter under multi-satellite a |
