    Thermal Control Design of Lunar SAR Antenna

    • Synthetic aperture radar (SAR) antenna is one of the important loads of remote sensing satellites. In the face of the complex external heat flow environment of the antenna outside the lunar orbital module, combined with the characteristics of the or-bit, the detailed external heat flow analysis of the antenna is carried out and the thermal design difficulties of the lunar environment are analyzed. The targeted thermal control design is carried out too, which solves the problem that the antenna circulates continuously between a large external heat flow and a small external heat flow in the polar orbit. The thermal simulation analysis of the antenna is carried out by using TMG software, and the thermal balance test is carried out by using the thermal simulator. The analysis and test results show that the temperature of each single antenna meets the index requirements. This paper is applicable to the planar SAR antenna and has certain reference significance for the thermal control design of active SAR antenna.
