摘　　要：An adaptive dwell scheduling algorithm for phased array radar(PAR)is proposed in this paper.The concept of online dynamic template is introduced,based on which a general pulse interleaving technique for PAR is put forward.The pulse interleaving condition of the novel pulse interleaving is more intuitive and general.The traditional adaptive dwell scheduling algorithm combined with the general novel pulse interleaving technique results in the online adaptive dwell scheduling based on dynamic template for PAR is given.The proposed algorithm is suitable for radar tasks with multiple pulse repetition intervals(PRIs),which can be utilized in the actual radar system.For the purpose of further improving the scheduling efficiency,an efficient version is proposed.Simulation results demonstrate the effectiveness of the proposed algorithm and the efficient one.The proposed efficient algorithm can improve the time utilization ratio(TUR)by 9%,the hit value ratio(HVR)by 3.5%,and reduce the task drop ratio(TDR)by 6%in comparison with existing dwell scheduling algorithms considering pulse interleaving in PAR and the proposed efficient one.
