Proportional navigation guidance law is widely applied in the terminal guidance of the reentry vehicle. However, the guidance accuracy of the traditional PNG law is largely affected by the wind disturbance. To improve the impact precision, the proposed method applies a feedback of angular velocity deviation to the traditional PNG law. With the proposed method, the vehicle could satisfy the terminal constraints under large wind disturbance. Also, simulation results validate that the proposed method can well enhance the performance of the vehicle.
