摘要/Abstract

摘要： 锡林浩特草原陆表发射率光谱是利用陆表场地进行卫星遥感器红外通道绝对辐射定标和产品真实性检验的关键因子之一。基于光谱平滑的温度与发射率分离反演迭代算法,利用高精度的波曼(BOMEM MR154)傅立叶变换红外光谱仪和红外标准板,对锡林浩特草原陆表发射率光谱进行测量。获得了不同时间和观测条件下测量的陆表发射率光谱数据。利用该发射率光谱测量结果,可以利用锡林浩特草原对目前国内外主流的遥感卫星热红外通道进行在轨场地绝对辐射定标,并对热红外遥感产品进行真实性检验。

Abstract: The meadow surface emissivita spectra of the Xilinhaote grassland of China is one of the key factors for calibration of thermal infrared remote sensors using land surface. Based on the iterative spectrally smooth temperature/emissivity separation (ISSTES) algorithm, Xilinhaote meadow surface emissivity spectra were measured using a BOMEM MR154 Fourier transform spectroradiometer and infrared golden board. Emissivity spectra data were obtained at different times and land surface conditions. With these measured emissivity spectra, all of the mainstream thermal infrared remote sensors can be calibrated and validated using Xilinhaote meadow surface.
