Description
Thermal control device for radar antenna transceiver components Technical field [0001] The present invention relates to a satellite radar antenna, especially a thermal control device for a radar antenna transceiver assembly. Background technique Radar antenna transceiver assembly is the important stand-alone of radar antenna, whether its working performance is normal or not directly affects product work performance. The thermal control task of the radar antenna transceiver component is to control the temperature of the transceiver component within a specified range. because The transceiver components work in high-power pulses, and the heat capacity of the transceiver components is small, and the heat consumption during operation is large, so the transceiver components The thermal control design is one of the keys to the thermal control subsystem. Thermal control requirements for transceiver components generally include the following three parts; Temperature range: r...
