This paper will present quantatitive results of vegetation parameter extraction using inteferometric data collected using the TOPSAR and GeoSAR mapping instruments. These radar operate interferometrically at an range of frequencies from X-band to P-band. Radar data derived vegetation parameters are compared to LIDAR data and in situ measurements for a variety of canopy and terrain types. Comparison of how the different frequencies interact with the vegetation as a function of tree height, and incidence angle and canopy parameters will be presented.
