The development of imaging simulation is introduced and the principle of optical remote sensing is studied in the paper . and the solar radiance , the influence on radiance transmission by atmosphere , the spectral properties of ground object and the characteristics of photoelectric imaging system are analyzed 本文系统地介绍了国内外光学遥感器在成像仿真方面的发展概况，研究了光学遥感器成像过程的辐射传输的理论基础，分别对太阳辐射、大气对辐射传输的影响、地物的光谱特性和遥感器的特征进行了分析。
With the improvement and perfection of the remote sensing technology , the rise and the development toward ground resolution and spectrum resolution of remote sensing devices for plenty of remote sensing data have been seen , from which derive an obvious problem that how so big a mass of data can be transmitted to the surface from an outer space platform 随着遥感技术的不断发展和完善，获得大量遥感数据的遥感器不断涌现，并且向地面分辨率和光谱分辨率两个方向迅速发展，由此产生的一个明显问题是如何从空间平台上传输这样庞大的遥感数据到地面。
