Abstract:

For the multi-target penetrating netted radar system scenario, in order to effectively improve the interference effect and penetration success rate, formation trajectory planning is particularly important. Therefore, this paper firstly builds a trajectory planning model. Starting from the four aspects of the aircraft's own constraints, trajectory safety, constraints among aircrafts, and task completion effect, combined with the characteristics of the multi-syndrome jammers formation and its environment, a relatively complete trajectory planning criterion is proposed to form a new overall objective function. Secondly, in order to effectively describe the maneuver properties of each aircraft and the connection between the accompanying jammer and the target aircraft, and improve the algorithm' s search ability, a multi-spherical vector-based (MS) method is proposed. At the same time, in order to further improve the exploration and development capabilities of the proposed algorithm, a hybrid particle swarm optimization with track point by track point learning (TLHPSO) algorithm is proposed, and the two algorithms are combined to form MS-TLHPSO trajectory planning method. Finally, the simulation scenarios are constructed for verification. The comparison results show that the MS method and the TLHPSO optimization algorithm have obvious advantages in the ability to find the optimal value. The proposed algorithm in this paper is superior to other algorithms in terms of the average value of the optimal solution in different initial scenarios, which fully shows that the algorithm in this paper can plan formation tracks with higher reliability under the premise of ensuring stability.
