A Method for Mining and Analyzing the Association of Air Targets
Quickly and accurately mining and analyzing the target association relationship contained in radar historical data can provide assistance for the study of air target activity law,target identification and judgment,and give full play to the role of historical data.According to the space-time characteristics of the target,a new method of mining and analyzing the association relationship of air targets is designed.A time matching method is designed to generate time correlation data sets.A spatial association metric is designed to generate spatial association data sets.Dynamic time warping(DTW)and spanning tree algorithm are used to match and search the air targets with associated relations,and generate the set of associated relations.After digital simulation verification,this method can effectively mine the historical information of radar data and find the correlation rules between targets.
