Abstract
In order to increase the impact angle of upper armor attack trajectory and increase the damage effect of anti-tank missile, the missile-target relative motion model of terminal guidance phase was derived. A new guidance law called bias proportional navigation guidance law based on terminal impact angle constraint was proposed, the influence of impact angle constraint on normal overload was studied and a control scheme of blind area was designed to decrease the normal overload at hit point. At last, the new guidance law was compared with conventional proportional navigation guidance law and two other improved proportional navigation guidance law based on trajectory simulation. Results of the simulation show that the new guidance law has better effect on control impact angle and high impact accuracy.
