摘要
FY-3卫星微波成像仪用于大气微波遥感、海洋微波遥感和陆地微波遥感;是气象、海洋和灾害监测的重要遥感手段之一。微波成像仪在轨运行时能否获取有价值的探测资料,得到定量化的应用和真正的业务使用,主要取决于微波成像仪能否进行精确定标。为了使地面的定标的数据能应用于在轨,试验时必须模拟在轨环境,即必须地面在真空环境下定标,本文主要介绍了FY-3卫星微波成像采用的真空定标测试系统,真空定标方法,并对将要发射的FY-3(04)星微波成像仪真空定标试验结果进行了分析,获得了微波成像仪真空定标灵敏度、线性度、非线性偏差和在轨定标参数。
Microwave Radiation Imager of FY-3 satellite, which is used in the area of air remote sensing, ocean remote sensing and earth remote sensing, is one of the important means of monitoring climate change, ocean and other disaster. Whether the microwave imaging radiometer can obtain useful sounding information, and achieve quantitative application and real business use or not when it is running in orbit, it mainly depends on the accuracy of calibration. The vacuum calibration test must be simulated orbit environment in order to make the calibration data can be applied in orbit. The paper introduce the vacuum calibration test system and method, which adopted by FY-3 satellite Microwave Radiation Imager. At last the vacuum calibration sensitivity, linearity, nonlinear and on-orbit calibration parameters are obtained through analyse the test results of FY-3(04) satellite vacuum calibration.
