In order to make the terminal sliding mode guidance law have better convergence effect and guidance precision, an adaptive variable index reaching law had been designed, and the influence of the parameters of sliding mode control law on ballistic was analyzed. The simulation results indicate that the system can effectively weaken the chattering in the process of reaching the sliding surface, and can eliminate chattering when approaching the sliding surface under the new adaptive exponential reaching law designed in this paper. The optimal parameter was attained through a lot of experiments, and the guidance precision of the guidance law of this optimal parameter is higher than that of the traditional sliding mode control guidance law.
