  • In space constrained tactical missiles, the size of seeker antenna servomechanism was restricted strictly, and rate gyroscope stabilization platform failed to work very well. The strapdown stabilization technique can be applied to stabilize line-of-sight(LOS). Based on configuration feature and stabilizing principle, a complete gimbal kinematics and dynamics model of two-degree-of-freedom strapdown antenna platform was achieved via coordinate transformation. The gimbal coupling characteristics was analyzed and simulated. Analysis indicates that main differences between strapdown stabilization platform and rate gyroscope stabilization platform lies in information obtaining and control mode. The rate gyroscope platform gets stability using hardware directly, while strapdown platform bases on software compensation. Simulating also shows that coupling between gimbals and missile body is strong, which need take effect measures to isolate. While cross coupling between outer gimbal and inner gimbal is weak, which can be ignored in practice. Results obtained will be a theoretical foundation for the further study of strapdown antenna platform, and it will be a engineering design suggestion for LOS stabilized system of miniaturized seeker.
