摘要
介绍了星载相控阵天线一体化热设计的方法,利用不同的仿真软件分析了天线热分布、结构变形等情况,通过建立热变形对天线电性能影响的仿真模型,验证热设计是否能满足电性能要求,并以电性能最优为目标实现最优的热设计。最后,针对星载SAR天线产品验证文中设计方法的工程可实现性。
The integrated thermal design of spaceborne phased array antenna is introduced. The temperature distribution and deforma- tion data of antenna in different conditions are obtained by use different simulation software. A mathematical model for antenna elec- trical properties is established, based on the temperature distribution and deformation of antenna. The thermal design can meet anten- na electrical performance is verify. The goal for antenna electric performance optimization is achieved by mechanical, electrical, ther- mal co-design. The computer simulation results of an spaceborne phased array antenna, by which the integrated design was validated.
