Strap-down seeker stabilization and tracking is a new digital technique which has a broad application prospect. Strap-down seeker technology due to seeker miniaturization and low cost has considerable significance. This paper presents a reasonable program for strap-down seeker stabilization and tracking ,finishes the controller design and simulation of the stability and tracking loop . The simulation demonstrate that the decoupling coefficient of the strap-down seeker meets the technical requirements and has good tracking performance.
