The precision strike to high value targets has become the main characteristics of the modern war. For attacking those deeply underground targets with hard protection, the penetration warhead which can penetrate the steel concrete up to over ten meters is used. In addition, to grantee a successful strike, some trajectory constraints should be met. In this paper, the trajectory shaping guidance law with terminal constraints is discussed in detail. Also, the guidance law with the requirement of a large impact angle is proposed. The implementation with engineering applications of this guidance law has a good value for precision guided weapons.
