According to the resources, missions and restraints, a scheduling algorithm based on view period windows refreshing is put forward and the model is established. Considering the multi-window multi-antenna structure and mission priority (PRI), the mission is scheduled reasonably and the time window is refreshed by the scheduling operation: the confirmed operator of current mission scheduling time and the refreshing of the following mission view period window. The PRI is considered as parameter in cost calculation and the scheduling project is optimized by genetic algorithm. The simulation scene includes 4 user satellites, 3 antennas and 32 missions. The simulation result reveals that the algorithm can obtain satisfactory results in both time and optimization, which is suitable in multi-mission and multi-antenna recourse scheduling.
