Study on basic principles of tri-axial stabilization for flat SOTM on vehicle

This paper is based on stabilization and insulation of vehicle attitude changes for flat SOTM. According to study on tri-axial stabilization principles and beam tilting techniques, the structure applying mechanical compensation for antenna azimuth as well as elevation and electronic compensation for polarization is set, the simulation results indicate that beam tilting technique could reduce antenna height effectively while the influences on antenna gain will increase and main lobe width will broaden with increment of tilting angle, and the structure that azimuth and elevation gyros are mounted on antenna elevation revolving table and polarization gyro is mounted on azimuth revolving tray or elevation revolving table could provide good work environments for gyros and brevity compensation equation to insulate vehicle attitude motions.
