Glide-warhead long flies in near space where aerodynamic environment is complicated, so the entry precision can not be guaranteed. In order to realize accurate attack and considering the demand for attack angle control, the motion equation of glide warhead at terminal phase was built in target coordinates, the dive guidance law based on expanded proportion guidance with terminal-velocity direction control was derived. Simulation results show that when parameters at the dive beginning point are reasonable, method in this paper performs efficiently to control the precision of attack angle.
