Abstract

The authors report millimeter-wave backscattering measurements of various tree types during the 1987 growing season at Amherst, Massachusetts. The data indicate that the millimeter-wave backscatter increases as deciduous trees become fully foliated, and decreases as leaves drop off during the fall season. Coniferous needle trees are seen to have almost constant backscatter. A simple model based on geometrical optics shows that the backscatter of deciduous trees can be characterized in terms of three ground-truth parameters.
