近期,航天科工二院203所将为一家高科技企业提供两套真空定标源,这是该所真空定标源首次实现产品化。据悉,203所设计的定标源能通过提供标准亮温度,对微波温度计、微波湿度计、微波成像仪进行测试,确保星载辐射计测得的亮温度数据准确可靠。该所曾先后为海洋、风云系列卫星定标,定标是星载微波有效载荷发射前的关键工作。被动星载辐射计,在发射之前必须进行定标试验,否则数据将无法定量应用。此次203所设计的定标源具有
Recently, 203 of Aerospace Science and Industry Institute No. 2 will provide two sets of vacuum calibration sources for a high-tech enterprise, which is the first time that the vacuum calibration source of this institute has been commercialized. It is reported that 203 calibration source designed to provide standard bright temperature, microwave thermometer, microwave hygrometer, microwave imager to test to ensure that the space temperature radiometer measured bright temperature data is accurate and reliable. The institute has successively calibrated the satellites for the oceans and the Fengyun series. Calibration is the key work before the launch of the spaceborne microwave payload. Passive spaceborne radiometer, calibration must be carried out before launch, or the data will not be quantitative applications. The 203 design of the calibration source has
