Theoretical Modelling Study on the Relationship between Multi-Frequency Microwave Vegetation Index and Vegetation properties(optical depth and single scattering albedo)
This paper presents a theoretical study of derivation Microwave Vegetation Indices(MVIs)in different pairs of frequencies using two methods.In the first method calculating MVI in different frequencies based on Matrix Doubling Model(to take in to account multi scattering effects)has been done and analyzed in various soil properties.The second method was based on MVI theoretical basis and its independency to underlying soil surface signals.Comparing the results from two methods with vegetation properties(single scattering albedo and optical depth)indicated partial correlation between MVI from first method and optical depth,and full correlation between MVI from second method and vegetation properties.The second method to derive MVI can be used widely in global microwave vegetation monitoring.
