Research of guidance law of missile with terminal angular constraint

At present, there is a more popular topic to do research about hard target and underground target. More and more precision weapons equip with penetration warhead. But to show the best penetration performance, there should be a strict terminal angular constraint. Thus, the research about trajectory and terminal guidance law of penetration missile will supply more theoretical basis for the design of penetration missile. The paper presents a guidance law and does research work about realizability in Engineering.
