According to the requirements of the servo mechanism of airborne full polarization microwave radiometer, the structure was designed and divided into two parts: the azimuth mechanism and the pinch mechanism, which can scan the ground 360° continuously without dead angle. Three-dimensional model of airborne full polarization microwave radiometer was designed using CATIA in this paper. The static analysis, modal analysis and vibration analysis of the servo mechanism of airborne full polarization microwave radiometer were performed using ANSYS. The analysis results showed that the structure of the device satisfied the strength and stiffness requirements. This thesis theoretically studied the position and posture of the servo mechanism. According to the Euler coordinate transformation theory, the velocity equation, acceleration equation and transmitting torque equation were derived. By simulating the physical model of the device using ADMAS, the variation law of displacement, velocity, and acceleration over time was obtained, which provided the foundation for actual motion and control system design.
