To address the problems in the application of aircraft swarms in active cooperative localization with one transmitter and multiple receivers,the optimal configuration and the trajectory optimization method for active cooperative localization are studied to further improve the localization accuracy.Firstly,the model of active cooperative localization using one transmitter and multiple receivers is established.Based on this model,the optimal geometric configuration of target localization with different number of receivers is derived based on A-optimality criterion and D-optimality criterion respectively,and the analytical solution of the optimal configuration is analyzed to provide theoretical support for the aircraft swarm's trajectory optimization.Secondly,the obtained optimal configuration is applied to the aircraft swarm's trajectory planning and an active localization method based on A/D-optimality criteria is proposed.Through simulation experiments,the accuracy of active localization for the aircraft swarm with one transmitter and multiple receivers after trajectory optimization has been significantly improved,indicating the effectiveness of trajectory optimization in active cooperative localization for aircraft swarms.
