其他摘要 | A spectrum-tunable ground scenery spectrum radiation source,using LEDs and bromine tungsten lamp as luminescence media,was introduced.System structure and control of the spectrum radiation source was expounded in detail.In order to simulate various ground scenery spectrum distribution with different shapes,aground scenery spectral database was established in the control system.An improved genetic algorithm was proposed,and a large number of ground scenery spectra were produced by the simulator.Spectral similarity and the average spectral matching error of several typical ground scenery spectra were further analyzed.Spectral similarity of red bands,green bands,blue bands and near-infrared spectral band also was discussed. When the radiance of the target was 50W·(m2·sr)-1,the average spectral matching error was less than 10%and spectral similarity was greater than 0.9,up to 0.983.Spectral similarity of red band,green band,blue band and near-infrared band(especially green band and near-infrared band)was less than that of full-band.Compared with blue band and red band,spectral similarity of green band and near-infrared band low-amplitude maximum can rearch50%.Ground scenery spectrum radiation source can be used as radiometric calibration source for optical remote sensor,and calibration error,which is caused by objectives and calibration sources spectral mismatch,can be effectively reduced. |
