Space-borne radar antenna temperature control device

The invention provides a satellite-borne radar antenna temperature control device, and relates to the technical field of radar antennas. Comprising a mounting plate; the first high heat conduction component and the radio frequency functional component are correspondingly arranged in the mounting plate; the first thermal control coating is arranged on the lower surface of the mounting plate; the second thermal control coating is arranged on the upper radiating surface of the antenna radiating unit of the radar antenna; the third thermal control coating is arranged on the lower radiating surface of the antenna radiating unit of the radar antenna; and the heat insulation part wraps the rest surfaces of the radar antenna except the lower radiating surface of the antenna radiating unit, and the thermal control device can improve the temperature uniformity of the multi-band radio frequency assembly of the radar antenna and the adaptability of a multi-satellite networking satellite constellation space thermal enviro
