Mission Planning for Cued Search of Cooperative Anti-Stealth Detection Based on PPSO-MPC

To solve the cued search problem when ESMs and radars cooperate with each other in anti-stealth detection,a MPC-based(Model Predictive Control) mission planning frame for cued search is proposed,and the targets' states predictive model and on-line receding optimization model are established based on the MPC theory.Then,this paper puts forward an improved parallel PSO(Particle Swarm Optimization) algorithm to solve the problem.Concretely,a high-dimensional matrix mode is designed for particle coding,a scale-factor is imported for boundary restriction,a probabilistic model is proposed for processing discrete variable,and a new multi-swarm parallel strategy called MM-SS(Multi-Master-Single-Slave) is presented for promoting optimization efficiency.Experiments show that the established model realizes an efficient control of multi-radars in condition of uncertainty and multiple targets,and that the proposed algorithm can solve the receding optimization problem efficiently.That is,the validity of the model and algorithm is demonstrated.
