| Abstract: | The space-borne antenna is in a complex temperature environment when traveling in orbit, which leads to a serious thermal distortion, to influence the electrical property of the antenna. According to the characteristics of the thermal distortion test, a thermal distortion test and modeling integrated analysis method is introduced. The method is briefly introduced in this paper, including the thermal distortion test project, and the simulation model, and the results of test are compared with the results of simulation. The verification method of the thermal distortion test and analysis can play an important role in the design of the large space-borne antenna. |
