A stealthy route planning algorithm for the fourth generation fighters

During traditional route planning, the fighter is always seen as a point without considering the effect flying attitude, which results in the result of route planning is often rough and unusable. Since flying attitude of the fourth generation fighter affects its stealth heavily, this paper considers the effect of the flying attitude of the fourth generation fighter to route planning, and supposes that radar threaten can be avoided (when maximal probability detected by radar is less than 20%). Based on the above conditions, this paper gives stealthy route planning algorithm for the fourth generation fighter. Simulation results show the algorithm is reasonable, effective and usable.
