The structure of oriented vegetation from polarimetric interferometry

Polarimetric radar interferometry is much more sensitive to the distributio n of oriented objects in a vegetated land surface than either polarimetry o r interferometry alone, This paper shows that single-baseline polarimetric interferometry can be used to estimate the heights of oriented-vegetation v olumes and underlying topography, while at least two baselines are needed f ur randomly oriented volumes. Single-baseline, calculated vegetation-height accuracies are in the range of 2-8 m for reasonable levels of vegetation o rientation in forest canopies.
