On Several Topics in the Theoretical Modeling of Remote Sensing
遥感理论模式研究的几个问题

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.
