Application of Model Analysis Based on FEM to Design of Radar Structure

Kejun Wang

Abstract

Based on understanding of radar products of our institute,this paper analyses structural design of two important subsystems of radar system,namely the antenna pedestal and antenna.The concept and simplified method of establishing FEM of these two subsystems to complete model analysis are summarized,and model analysis for an elevation antenna pedestal with a standing azimuth axis and an antenna with main reflector and sub-reflector by ANSYS software is carried out.
