Abstract：For developing a remote sensor, the selection of operating waveband is one of the most important factors for detecting and identifying target. In the present paper, the changes of atmospheric effects and imagery quality are simulated due to the increase in the response wave range of optical remote sensor from 0.50-0.85 mm to 0.45-0.90 mm by using MODTRAN4. The experimental results show that there is a slight increase of the adverse factors, including atmospheric transmittance, path radiance, and adjacency effect, after the working waveband has been widened. The disadvantages compared with the improvement in incident radiance，target-background contrast and image quality are negligible. In summary, the scheme of 0.45-0.90 mm is superior to 0.50-0.85 mm and it has been more widely used in the on-orbit operation high-resolution satellite sensor.
