Scatterometer resolution enhancement

Scatterometers can be effective for large scale monitoring of the Earth´s surface. However, their low resolution can limit the utility of the data. Thus, there is interest in resolution enhancement methods that can create high resolution imagery from scatterometer measurements. In this paper, a brief review of an iterative image reconstruction is presented, and the implications of this theory for enhanced resolution scatterometer imaging is presented. The result is that the multipass sample spacing is the single largest limiting factor in the reconstruction scheme, while the aperture function attenuation and noise level play secondary rolls in the limit of the enhanced resolution image reconstruction from scatterometer data
