Real-Time Dwell Scheduling Based on a Unified Pulse Interleaving Framework for Phased Array Radar

Dwell scheduling is a key for phased array radar to realize multi-function and it becomes especially challenging in complex tactical situations. In this manuscript, a real-time radar dwell scheduling algorithm based on a unified pulse interleaving framework is proposed. A unified pulse interleaving framework that can realize pulse interleaving analysis for phased array radars with different receiving modes is put forward, which greatly improves the time utilization of the system. Based on above framework, a real-time two-stage approach is proposed to solve the optimization problem of dwell scheduling. The importance and urgency criteria are guaranteed by the first pre-schedule stage, and the desired execution time criterion is improved at the second stage with the modified particle swarm optimization (PSO). Simulation results demonstrate that the proposed algorithm has better comprehensive scheduling performance than up-to-date algorithms that consider the pulse interleaving technique for both single beam and multiple beams receiving modes. Besides, the proposed algorithm can realize dwell scheduling in realtime.
