Microwave Absorbing Heat Flow Simulation System for Vacuum Thermal Test of Large Microwave Antenna

In this paper, we introduce a microwave absorbing heat flow simulation system for vacuum thermal test of large microwave antenna on spacecraft, which is mainly used for the vacuum thermal test of spacecraft microwave antenna. This method of microwave absorbing external heat flux not only meets the requirement of vacuum thermal test, but also can control the temperature of the antenna different part separately, and effectively simulate the temperature change of the antenna on the orbit.
