The radar stabilization system is designed to compensate the wave caused by ocean wave effectively and ensure the continuous and stable operation of shipborne radar in the changeable ocean environment. A new type of two-degree-of-freedom radar stabilization system is presented in this paper. By solving the steady-state isolation equation, we determine the relationship between the wave disturbance and the input attitude of the stabilization system, and explain its working mechanism. In order to estimate the maximum drive force required for the electric cylinder in the early stages of engineering design, we constructed the maximum drive force model in the limit state and calculated the maximum drive requirement in the extreme conditions. In order to verify the accuracy of the proposed driving force model, we use Adams software to create a simplified model and carry out kinematics and dynamics simulation according to the working principle of the system. This paper provides a valuable reference method for the design and research of radar stability system by deeply analyzing the motion characteristics and driving force characteristics of electric cylinder in different motion states.
