星载天线在轨热电耦合分析与电性能补偿
On-orbit thermoelectric coupling analysis and electrical performance compensation of spaceborne antennas
摘要
Abstract
During on-orbit service,spaceborne antennas are affected by the harsh space environment,causing structural deformation that severely impact their electrical performance.To address this issue,this paper proposes an electrical performance optimization method based on phase compensation.First,a hybrid high-low frequency algorithm is used to analyze the antenna's electrical performance during on-orbit service,exploring the impact of thermal deformation the antenna's performance.Then,using gain loss and pointing error as optimization objectives respectively,an optimization model is established,and the phase of the array feed is adjusted through a particle swarm optimization algorithm to compensate for the effects of thermal deformation on the antenna's electrical performance.Taking a parabolic cylindrical reflector antenna as an example,simulation results indicate that on-orbit thermal deformation has a significant impact on the antenna gain and pointing.After compensation,the antenna performance is restored to the ideal level,indicating that the proposed method can effectively compensate for the electrical performance degradation caused by thermal deformation.关键词
