Numerical Simulation and Comparison with Measurements for the Correlation of Active and Passive Microwave Remote Sensing
微波兰被动遥感相关特性的数值模拟和实验对比

Employing the model of a layer of continuous random medium with anunderlying rough surface, the bistatic scattering and back-scattering coefficients arecalculated. By using the reciprocity, the emissivity is also calculated. Numerical results simulate the change of the backscattering and emissivity of the vegetationcanopies and their correlation during whole growth period. Theoretical results arecompared with the measurements of active and passive remote sensing of severalvegetation canopies. The correlated characteristics of microwave active and passiveremote sensing are discussed.
