C-Band PolSAR Backscatter and PolInSAR Coherence-Based Modeling
243
Figure 10.10, it was observed that the volume backscatter component was successively followed
by HV and HV+ VH coherences, sigma- nought HV backscatter coefcient parameters. Therefore,
it could be identied that the most sensitive and important parameters predicted AGB with high
accuracy, yielding the lowest RMSE in return.
In the case of RFR model, the value of the coefcient of determination was 0.65, and the RMSE
value yielded was 24.33 Mg/ ha, as seen in Figure 10.11(a). In the case of the MLR model, the value
of the coefcient of determination was 0.54, and the RMSE ...
