Abstract: Impact of rolling and pitching of warship on radar antenna can be eliminated by ship-borne radar stabilizing platform system.The structure form,dynamic properties of the radar stabilizing platform are key to the transmitting accuracy of radar.This paper discusses in detail the structure design of a two-axial stabilizing platform.Drive power required for the stabilizing platform is computed by analyzing individual loads of the stabilizing platform.Finite element modeling and analysis are carried out by using ANSYS software.According to the analysis results,rationality of the structure design is verified.Finally,using the stabilizing platform,the impact of rolling and pitching of warship on a ship-borne radar antenna is successfully eliminated.
