Time matching strategy for missiles attack based upon pseudo spectral optimization prediction method

In the process of salvo attack of cruise missile, in order to solve the time matching problem occurring in the flight process, predicting online real-time trajectory optimization based on the pseudo spectral method under the condition of no-fly zones constraint, and the combination circular maneuver are presented. The whole route area of cruise missile is divided, and the method of forward search of no-fly zone to adjust the route online rapidly is provided. Simulation results show that the proposed method can make the cruise missile effectively consume the redundant time and bypass the no-fly zone successfully, the adjust distance is short, and can fly back to the original trajectory in the end of the adjustment, eventually achieve the goal of salvo attack.
