英文摘要：

A new guidance scheme is presented in this paper based on the requirement of battlefield to analyze the deeply strapdown miniature ammunition guidance system. According to the dynamics of miniature ammunition, a longitudinal channel model combining with its characteristics is set up. The critical problem of how to obtain guidance information for deeply strapdown guidance system is analyzed firstly. Then anangular rate decoupling approach is proposed in details. A program is built based on the dynamics and guidance information. A segmented guidance scheme that combines program guidance and proportional one is designed to complete the guidance of strapdown miniature ammunition. The feasibility of the segmented guidance scheme is verified by trajectory simulation, which provides a theoretical basis to the guidance design of the miniature ammunition.
