Abstract：A new guidance algorithm with threat avoidance ability and target sighting restraint is proposed for traditional staged guidance method lack of threat avoidance ability.Firstly,mathematic model of guid-ance is established based on relative velocity vector,second,the path restraint model is established based on threat avoidance,and guidance terminal restraint for target sighting is given.Value function is estab-lished based on rapidity,economical control and guiding precise,optimal control model for attack guidance is constructed with nonlinear boundary restraint,state restraint and path restraint.Gauss Pseudo spectral Method (GPM)is adopted to transform the problem into nonlinear programming problem.Simulation re-sult shows,this new guidance algorithm is effectively for threat avoidance and the missile launch require-ment is well satisfied by air combat requirement.
