摘要
为了满足星载光学遥感仪器红外定标试验和星载微波遥感仪器微波真空定标试验的需求,上海卫星工程研究所研制成一套专用空间环模设备,该套设备在红外定标用20K冷屏制冷方式的基础上,采用5台G-M制冷机组合冷却冷屏,冷屏温度可降至20 K以下。同时,该设备是国内第一台微波真空定标试验设备。试验证明设备各系统达到设计指标要求。
To calibrate the remote sensing infrared instruments and microwave instruments on satellites,a space environmental simulation facility is designed in Shanghai Institute of Satellite Engineering.The facility uses five G-M refrigerators to cool the cryo-panel to below 20 K in experiments.This is the first facility for the calibration of both microwave and infrared remote sensing instruments in China.It is shown by experiments that the performance of the facility can satisfy the requirements in the corresponding design specifications.
