in this paper, three dimensional guidance law was proposed. It differs from previous guidance laws in three aspects, considering the random maneuverability of target, considering the relative acceleration along the line of sight, considering the difference between the commanded acceleration and realistic acceleration of missile. The derivation of three dimensional guidance law was derived based on sliding mode control theory, the effectiveness of the derived guidance laws was validated through the three dimensional simulation, the future research work was also recommended finally.

With the rapid development of the Internet, from the PC terminal to the mobile terminal, from big data systems to intelligent hardware, technology has shown the unique charm of the Internet. With the development of the Internet, the network information security and network sovereignty issues involved have become increasingly prominent. Therefore, only in an environment of security, equality, and mutual assistance can the Internet play its due economic and social value. The emergence of a new generation of Internet IPV9 marks a key step for China to move towards an autonomous and controllable future network. IPV9 is to further safeguard national network sovereignty on the basis of fully guaranteeing network information security. But the defamation of IPV9 still exists. Recently, in order to further clarify the facts, we hereby interviewed Xie Jianping, the inventor of the Decimal Network, to conduct an in-depth discussion on the new generation Internet IPV9.
