3.2 Correlations of Parameters with EC at 60 cm depth
The various backscatter parameters were analysed for correlation with Electrical Conductivity (EC) and NDSI for both VH and VV polarisation channels. For σ0, β0 and γ0, high values of R2 statistics for correlation were given as shown in Figures 4. Figure 4 shows the correlative plots for σ0in VH and VV polarisation with Surface EC for all three dates, since C-band SAR waves are affected by the surface soil conditions and interacts with the surface soil ions as shown by Figure 4-
