Title    Rate of terminal guidance ammunition of the terminal   guidance of design and analysis                                                   

Abstract There are many kinds of terminal guidance projectile terminal guidance way, this article mainly proportional guidance law as terminal control mode, research to a certain large caliber guided artillery ballistic accuracy control problem, this terminal guidance ammunition flight principle and the design principle of rate of terminal guidance, the flight dynamics model is established, the analysis and design its rate of terminal guidance and terminal guidance control equation, the numerical analysis of the flight trajectory characteristics and terminal control effect, etc., to provide technical support for the development of the terminal guidance ammunition. The results indicate that proportional navigation with over-gravity compensation is suitable for attacking fixed or less mobile targets，and especially for hitting the top of the target，for its angle of fall is greater and the line of sight at the point of impact has

deflection and greater overload.

Keywords  Terminal guidance ammunition  Ballistic characteristics The gravity compensation  Rate of terminal guidance Proportional guidance law
