Abstract

Leaf area index (LAI) is an important biophysical parameter, and remote sensing provides the probability for the LAIretrieval. LAIinversion based on the model is the main orientation of the LAIretrieval, and the multi-angle data are important parameters in the model-based inversion. The new airborne multi-angle sensor AMTIScan obtain the simultaneous multi-angle and high-resolution data. Using the AMTISdata based on the three-dimensional radiative transfer model, an inversion experiment on a wheat field in Shunyi was carried out on the basis of the AMTISmulti-angle data and the prior information. And the result was verified with the measured LAIdata. The inversion precision and rate were improved by adjusting the soil classification and the matching table. The main errors in the process of inversion are also analyzed in this paper.
