摘要
根据矿物、岩石和不同矿床岩矿光谱特征,从遥感地质矿产的研究需求出发,进行多光谱波段模拟选择。将试验区机载成像光谱HyMap数据经大气传输模型模拟到中巴地球资源卫星1号(CBERS-1)的轨道高度,对所选的波段进行综合模拟、应用对比分析,提出我国后续资源卫星多光谱传感器在地质矿产应用上遥感波段的位置、波段的带宽和波段数目。
The ground material spectrum features is the base for the multi-spectral remote sensing. In this paper, based on the spectra of the minerals, rocks and deposits, the spectral simulation and band selection are developed from the requirement for remote sensing geology & mineral resources; By the using the 6s model of atmospheric transmittance, the data of the airborne imaging spectrometer HyMap is simulated on the orbit altitude of CBERS-1 sensor, then the completely simulation and the analysis of application comparison are done for remote sensing data of the chosen band. The band position, width and number are provided for the sensor of the post-continnued resources satellite in the geological remote sensing application.
