A flight path planning method based on DE(Differential Evolution) algorithm for hypersonic vehicle is proposed and simulated.Threat model is established.The model is projected into the equatorial plane.And a polynomial function with finite terms is used to approach the projection of actual flight path in the equatorial plane.So the flight path planning problem is simplified to the problem of searching the best series of values in the coefficient space of the polynomial function.Flight path in the equa-torial plane can be generated by DE algorithm considering hypersonic vehicle's characteristic.The actual flight path can be gen-erated according to corresponding relation.Simulation results show that the generated flight path can automatically avoid threat.
