An improved threat model of potential field theory is used to plan practical 3D track.Terrain,radar,and fire threats are classified and analyzed,and formulas are deduced.Search field is limited within a rectangle zone including the start point and destination,which reduces complexity of calculation and ensures convergence to destination.The flight line is confined by using the gradient restriction smoothing algorithm and curvature limit smoothing algorithm,which is suitable for aircraft mobility.
