Abstract: In order to solve the reentry guidance law design problem of hypersonic vehicle in complex environment, a design method of no-fly zone avoidance reentry guidance law is proposed aiming at the avoidance requirements of no-fly zone such as terrain, geopolitics and air defense interception in reentry process. The longitudinal guidance law realizes fast trajectory planning based on reentry flight corridor method. The lateral guidance law adopts the line-of-sight angle deviation corridor to realize the no-fly zone avoidance and target tracking, and the online prediction correction guidance module is designed according to the range error. The effectiveness of the longitudinal and lateral guidance laws is verified by numerical simulation. The simulation results show that the process constraint and the no-fly zone constraint can be satisfied.
