Simulation Analysis and Intelligent Computing about the Influence of Shipborne Radar Antenna Structure on Electric Axis

The antenna structure of shipborne radar is affected by many factors, among which the change of antenna structure is the key factor to be considered in the early stage of antenna design. In this paper, the factor affecting the antenna electrical axis by the antenna structure are analysed theoretically, and the finite element model for the mechanical analysis and calculation of the antenna structure is established by ANSYS. The deformation and stress of antenna structure under different load conditions are calculated, and the root mean square value of antenna reflector deformation under each load condition is given, so as to obtain the influence of antenna structure change on electric axis, which provides favorable data support for the subsequent revision of shafting error model.
