Abstract:An effective scheduling algorithm is very important for the phased array radar to optimize its performance, and the task priority assignment has crucial influence on radar performance. In this paper, a BP neural network is introduced to scheduling algorithm to assign priority for the target based on its flight parameters and track state instantaneously and adaptively. The proposed algorithm reasonably arranges the radar requests based on their priorities and time restriction, selects the most important of them to execute. The validity of the algorithm is proved by the results of the simulation.
