英文摘要：

The midcourse guidance law was designed for missile with variable sweep wings, which played a very important role in the whole process when designing missile. According to variable characteristic of the shape parameters, the model of trajectory optimization was built up for a swing-wing missile. And the glide trajectory was optimized. A midcourse guidance law for glide trajectory was promoted, which de- pends on tracking the motional virtual target. And the feasibility was verified through the simulation anal- ysis. The research results could provide reference to the overall design of guide missile with variable sweep wings.
