Abstract : This article studies a type of new model strap down terminal guidance system. It contains a strap down type guidance head, a set of strap down type inertial sensors, and in the three speed gyroscope and three line accelerometer are partially shared measurement components associated with navigation, guidance, and piloting instruments. The article presents a strap down terminal guidance design associated with the estimation of target status relative to missile movements in inertial coordinate systems, deriving the structures and mathematical models associated with the types of systems in question. It puts forward design algorithms for generalized Karman (phonetic) filters as well as optimal guidance patterns. Finally, use is made of digital simulations to empirically verify the feasibility of the systems ir question to handle close range, highly maneuverable targets.
