Aiming at the subjectivity of the time resource allocation and the low utility of the time resource in the air defense phased array radar

a novel online task interleaving scheduling algorithm was proposed by considering the internal structure of the task. On the basis of setting the importance and the urgency of the task into dynamic priorities

the algorithm can execute other task's transmitting period or receiving period during the task waiting period. The simulations show that the proposed algorithm significantly improves the successful scheduling ratio

the time utilization ratio

and the treat ratio of execution compared with the highest task mode priority and earliest deadline first (HPEDF) algorithm.
