Traditional scheduling algorithms in the phased array radar cannot be utilized to fully release multi-function potential of digital array radar.Aiming at this problem

an online interleaving scheduling algorithm is proposed on the basis of the task internal structure.By decomposing the interleaving scheduling analysis into the time resource constraint analysis and the energy resource constraint analysis

the algorithm is able to interleave all kinds of tasks as far as they meet the resource constraints.Thereby not only the waiting duration is utilized to execute other task's transmitting duration or receiving duration

but also receiving durations of different tasks are able to be overlapped.The simulation results show that

due to the efficient usage of the waiting duration and the receiving duration

the proposed algorithm effectively improves the successful scheduling ratio

the high value ratio and the time utilization ratio compared with the three existing algorithms.
