Research on timing-critical mission based on dynamic path planning

With the increasing complication of the battlefield and the increasing diversities of the military mission, UCAVs are required to reach targets at times within a certain tolerance in order to achieve the necessary sequencing of mission goals. Time error signal is obtained from the real time-to-go and the estimated time-to-go by adopting a simple online time-to-go estimation method. According to the time error, the yaw maneuvering command is generated and dynamic path planning on the basis of the prescribed path is done to control impact time. The results of simulation show the reasonableness of the method. Dynamic path planning for timing-critical mission can be used in path planning of coordinated rendezvous of UAVs.
