Time window of ship-to-air missile weapon

In this paper, the time window of ship-to-air missile is calculated in order to determine the launching opportunity. The shapes and characteristic parameters of emitter region and firing area are introduced and calculated. The mobility of anti-ship missile is considered in the simulation. Simulation results indicate that the established model is reasonable. The calculating result can be used for the threat evaluation and weapon target assignment of ship-to-air missile weapon system.
