Abstract:

In order to solve the problems of large number of targets and uncertain and inaccurate information in situation, a target grouping algorithm based on interval number clustering is proposed. Firstly, aiming at the problem of sensor measurement data with error and incomplete, the interval number is used to describe the characteristics of the target detected by the sensor. Then, a new distance measure is defined to make use of interval number information effectively, and an improved interval number clustering target grouping algorithm is given. Finally, four types of independent interval data sets are constructed to classify and test the interval data. Through typical scenario, multiple types of target entities are set, and spatial groupring and task grouping are carried out based on the elements such as target spatial location, motion characteristics and attributes. Simulation results show that the algorithm can effectively group targets and has strong stability.
