偏振成像技术在大气探测、环境监测、资源普查和军事侦察应用中具有十分重要的作用,该技术在航空遥感和空间遥感中已经开始使用。临近空间飞行器的发展为偏振成像遥感提供了新的应用舞台,并显示出了明显的优势。本文介绍偏振原理、偏振探测和成像方式,针对临近空间飞行器给出了一种凝视式高分辨率偏振成像系统的方案,并通过论证和分析性能得出了该方案实现的可行性。

Polarization imaging plays a very important role in the applications such as atmospheric de-tection, environmental monitoring, resource investigation and military reconnaissance. It has been used in aerial and space remote sensing. The development of near-space vehicles provides a new platform for polarization imaging remote sensing and shows its remarkable dominance. The polarization principle and polarization detection and imaging are presented. The design scheme of a staring high resolution polar- ization imaging system for near-space vehicles is given and its feasibility is verified after its performance is analyzed.
