spectral radiance measurement
1.The task and requirement of HJ-1A satellite CCD camera are introduced, then the paper analyzes chief elements which effect on the incident spectral radiance of HJ-1A satellite CCD camera And get different incident spectral radiance of CCD camera in different conditions through "6S" software According as the observation ability of every waveband and the spectral characteristic of ground, the maximum value of incident spectral radiance of every waveband is finally given
