Study on remote sensing radiation transfer model

In order to perform the remote sensing models´ collaborative retrieval through different medium and different bands, the deep relationship of Radiation Transfer Equation (RTE) in different medium should be understood in advance. Therefore, the author deduced the “classical RTE” on the basis of the radiation transfer theory, and then analyzed the hidden relationship among the RTE in the atmosphere, soil, and water body. The results reveal that the difference of different medium´s RTE mostly derives from the mathematical descriptions about their optical properties, and that these equations have great relevance with each other. Due to this, the “classical RTE” is just like an inner “bridge” to link different equations together.
