| 摘 要： | 传统人工场地试验方法效费比较低、单次试验不确定性大,难以满足卫星载荷高频次的辐射特性变化监测等,本文利用敦煌辐射定标场(以下称“敦煌场”)自动化设备,对GF-6卫星PMS传感器在轨运行以来的辐射特性进行了自动变化监测试验。经过4次同步试验数据分析表明,GF-6卫星自2018年发射以来,PMS相机辐射特性变化小于5%。

| Abstract: | The traditional ground-based method has a low cost-effectiveness and large uncertainty of single experiment, which can not meet the requirement of high frequency and high-precision radiation performance change monitoring of satellite payloads. A based on automated method is applied on radiometric performance change monitoring of GF-6 pan multi-spectral sensor(PMS) based on the Dunhuang radiation site (hereinafter referred to as "Dunhuang site"). The results show that decay of radiation performance is less than 5% since GF-6's launch. |
