Abstract:

High-precision positioning of aircraft clusters is a necessary prerequisite for executing cooperative tasks. Aiming at the scenarios of multi target collaborative detection where the Global Navigation Satellite System (GNSS) is denied and environmental feature information is limited, a cooperative positioning method based on the topological features of target groups is proposed. This method uses only the distance measurements from the data link within the cluster and the multi target detection information. A distance-measurement polyhedron is constructed using multidimensional scaling (MDS), and target association is performed based on the three-dimensional topological features of the target group. A relative positioning optimization model is then established. The optimal solution for the polyhedron’s attitude is obtained by using an improved particle swarm optimization (PSO) algorithm with a compression factor. Simulation results demonstrate that high relative positioning accuracy of the cluster can be achieved. Combined with the inertial navigation system (INS) position output, the absolute positioning accuracy of the aircraft cluster is also improved.

Key words: relative positioning, target association, multidimensional scaling (MDS), particle swarm optimization (PSO)
