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 deformation data of antenna in different conditions are obtained by use different simulation software. A mathematical model for antenna electrical properties is established, based on the temperature distribution and deformation of antenna. The thermal design can meet antenna electrical performance is verify. The goal for antenna electric performance optimization is achieved by mechanical, electrical, thermal co-design. The computer simulation results of an spaceborne phased array antenna, by which the integrated design was validated.
