Analysis and Trajectory Design for Supersonic Target

To seek an inexpensive supersonic target,characteristics of various targets are analyzed,its tactical and technical specifications are drafted,and a refitting scheme using big-caliber supersonic rockets is put forward. An optimization model to meet tactical and technical requirements is built,in which the speed and the trajectory angle at the end of active phase are used as the design variables and the horizontal flight distance of the target is used as the objective function. The simulated results show that the method is reasonable and feasible.
