To study the terminal guidance problem of maneuvering vehicle under the multiple constraints, an optimal guidance law is proposed. Considering of the terminal position, impact angle constraint and overload requirement. Firstly, the linear dynamic model of terminal guidance is established, and the expression of acceleration command is inferred by the Schwartz inequality theorem, then the form which is convenient for engineering application is presented. The features of guidance coefficient is obtained by analyzing the influence of guidance order to overload and trajectory characteristics. At last, the terminal guidance law is proposed. It is showed that the guidance law can both reduce the overload, and meet the command of maneuvering, impact angle constraint and attack accuracy by simulations.
