英文摘要： As a new multifunction radar system, digital array radar has the advantages of flexible work mode and resource sharing capability. With the effective resource scheduling technique, the surveillance performance of the radar system can be improved evidently..Firstly, the character of work mode is analyzed for the digital array radar, and the resource scheduling flow of radar task and beam dwell is proposed. Secondly, based on the radar work mode, the model of beam dwell is bulit and the key parameters, time window and priority, are studied. And the constraint condition for the time and energy resource is presented. Thirdly, the adaptive scheduling algorithm for radar beam dwell is studied and designed based on the task scheduling in real time system and the pulse interleaving technique. Lastly, the quantified performance metric indices are presented according to the task scheduling and radar performance respectively, and the resource scheduling algorithm proposed is evaluated. Furthermore the effectivity of the method presented will be validated with the real data of multifunction radar equipment. The research results can improve the radar system surveillance performance and efficiency of reousce utilization, as well as provide the key technical support for the automatization and intelligence of the multifunction digital array radar system.
