To research exo atmospheric interceptor with pulse jet, considering the measurement noise of rotation rate of LOS (line of sight) and error of estimating relative distance between missile and target, the LOS rate was predicted by state, control input, measurement noise of LOS and estimation error of relative distance. The switching guidance law was designed on the basis of predictive control, and switching curve was derived by analysis. Stabilization of the guidance system with switching guidance law was analyzed by using Lyapunov method. The simulation result shows that the direct impact can be realized by the guidance law proposed in this paper while the LOS rate and the relative distance between missile and target measured unexactly.
