吸波热沉在微波雷达成像卫星真空热试验中的应用
Application of microwave absorbing heat sink in the thermal vacuum test of microwave radar imaging satellite
摘要
Abstract
In the vacuum thermal test for the SAR satellite, special measures should be taken to absorb the high power microwave emitted by the transmitter-receiver subassembly to protect it from damage. This paper introduces a new heat flux simulation device, with the functions of both absorbing the wave and simulating the heat flux. In order to verify the validity of the microwave absorbing heat sink, a calibration experiment is carried out. The experimental results show that the heat sink can meet the requirements of external flux precision for the thermal vacuum test, with a bias not more than 4%. The heat sink has been successfully applied in the thermal vacuum test of a SAR satellite.关键词
