摘要：

This paper presents an example showing how VHF SAR images acquired over the same area, but with different look directions, can be combined in order to improve signal-to-noise ratio and spatial resolution. It is demonstrated that when combining images with 360degrees of aspect variation, the spatial resolution approaches the theoretical limit set by diffraction. Results are presented showing that it is possible to resolve individual trees in VHF SAR images over reasonably dense coniferous forests, and that there is good correlation between stem volume of individual trees and amplitude in combined SAR images.
