基于干扰仪平台上的天线建模及参数敏感度分析OA

Aiming at the high cost in the electromagnetic design process caused by time-consuming traditional modeling and analysis methods for complex platforms integrated with multiple antennas,a simplified antenna modeling method based on parameter sensitivity analysis is proposed in this paper.Based on the jammer platform,the influence of each structural parameter of the coaxial collinear antenna on electromagnetic radiation performance is quantified by global sensitivity analysis.Simulation results show that some antenna parameters can be simplified while ensuring the error between simulation and actual measurement is within 10%,thus shortening the time of antenna modeling and simulation,significantly improving antenna design efficiency,and providing effective technical support for rapid modeling of complex electromagnetic systems.
