Dwell scheduling algorithm based on analyzing scheduling interval for digital array radar

Abstract:

Aiming at the problem of beam-dwell scheduling for digital array radar，the algorithm based on analyzing scheduling interval was studied. This algorithm analyzed the dwells applied to be executed in one scheduling interval and introduced pulse interleaving. The scheduling criterion took both priorities and deadlines into account fully，with the Task Drop Ratio，Hit Value Ratio，Time Utilization Ratio as evaluation indexes. The simulation results showed that the modified deadline criterion mainly emphasized the urgency of tasks，while the modified priority criterion mainly emphasized the importance of tasks；the deadline-priority and priority-deadline scheduling criterions could make good balance between urgency and importance，thus superior to other criterions in overall performances.
