遥感理论模式研究的几个问题

本文简要地评论近年来微波遥感理论模式研究的进展,主要包括遥感对象理论模拟的随机离散散射粒子介质,连续随机介质,和随机粗糙表面的电磁散射和热辐射的理论,定量的数值求解方法,以及它们在地表植被、土壤、冰雪、大气云雨、海冰、风驱海面等主动和被动遥感中的应用。随着今后遥感技术的发展,要更为精细地模拟自然界中遥感对象及其环境,给出定量的数学物理学方法,进行定量的数据分析和遥感参数反演,还有大量的工作有待于研究。本文讨论了当今遥感理论模式研究中还存在的问题,提出了今后要予以研究的若干个方向性工作。

On Several Topics in the Theoretical Modeling of Remote Sensing

The progress in theoretical modeling of microwave remote sensing in recent years is briefly reviewed in this paper. As the models for the objects of remote sensing the theories and numerical approaches of electromagnetic scattering and thermal emission of random discrete scatterers, continuous random media, and randomly rough surface are discussed. The applications in both active and passive remote sensing of the earth terrain, vegetation canopy, soil, snow and ice, atmospheric cloud and rain, sea ice, and sea surface driven by wind, etc. are also introduced. With the future development of the remote sensing technology, further efforts to develop more accurate models and quantitative mathematical physical approaches for remote sensing of the nature, and to develop numerical data analysis and parameter retrieval must be done. Some comments on the research progress in theoretical modeling of remote sensing are discussed, and several interesting and important topics for future research are pointed out.
