The objective of this study was to determine whether leaf area index (LAI) in temperate mixed forests is best estimated using multiple-return airborne laser scanning (lidar) data or dual-band, single-pass interferometric synthetic aperture radar data

The GeoSAR single-pass P-band and X-band IFSAR system was employed 09 April 2012 to acquire ice data over the city of Barrow, Alaska, extending into the Chukchi Sea to the west and the Beaufort Sea to the northeast. The acquisition covered two back-t

At present there is no consensus as to which remote sensing technologies are appropriate for tropical forest biomass estimation. Cloud cover in the tropics and biomass saturation suggest that a combination of low-frequency SAR and interferometry (eit

GeoSAR is a single pass, dual frequency (X-band and P-band) interferometric mapping radar designed to map both top vegetation canopies and the terrain beneath the canopy. This system was developed from 1998–2003 as a joint effort of NASA JPL and Ea

A new technique is described for improving transform encoded signal reconstruction by extrapolating missing coefficients in the transform domain. The extrapolation algorithm is very simple and it can easily be incorporated into one-and two-dimensiona
