In order to support air-to-surface multi-target attacksthe model of air-to-surface multi-target common release zone is studiedand the definition of common release zone is given.A solution of multi-target common release zone based on polygon intersection is given.The longest attacking route of the common release zone and the entry point are modeled.Furthermorethe method of batch division is proposed to support the whole process of attacking.The method is a deterministic algorithm with determined computational complexity and high precisionwhich is suitable for airborne real-time calculation environment.Finallythe model of air-to-surface multi-target attacks is simulated and implementedoutputting the common release zone and batch division results.The simulation results show that the model of multi-target attacking is correct and effectivewhich can realize batch division and attacking route planning in air-to-surface multi-target attacks.
