Incidence Angle Normalization of Radar Backscatter Data
IEEE Transactions on Geoscience and Remote Sensing, 2013The National Aeronautics and Space Administration's (NASA) proposed Soil Moisture Active Passive (SMAP) satellite mission ( ~ 2014) will include a radar system that will provide L-band multi-polarization backscatter at a constant incidence angle of 40 °.

Radar Backscatter from the Earth's Ionosphere
IEEE Transactions on Military Electronics, 1964The role of radar backscatter observations in ionospheric studies is outlined. The theoretical developments are described that form the basis for ground-based measurements of electron density, electron temperature, ion temperature, and ionic composition at ionospheric heights, Observations of the first three parameters have been successful. Observation

Radar backscatter characteristics of trees at 215 GHz
IEEE Transactions on Geoscience and Remote Sensing, 1988Millimeter-wave backscatter measurements are presented for various tree types taken during the 1987 growing season at Amherst, Massachusetts. These measurements were taken with a 215-GHz radar system that is capable of measuring backscatter for the VV (vertical transmit, vertical received), HH (horizontal transmit, horizontal received), VH, and HV ...

Fractal polarization signature of radar backscattering variations
2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016A new type of polarization signatures for radar imaging of the earth's cover is proposed. These signatures allow us to determine the degree of spatial variations of the backscattering coefficient on the basis of the fractal approach. The azimuthal dependence of the radar backscattering spatial variations is discovered when analyzing backscattering from

Radar backscattering of forest stands
International Journal of Remote Sensing, 1985Abstract Research on the potential applications of microwave remote sensing in agriculture is conducted in the Netherlands by the ROVE team. Since active microwave remote sensing, featuring its all-weather capability, also seems to be a promising tool for forest classification, especially on a global scale, the Wageningen Agricultural University ...

Wind velocity and cross polarization radar backscatter
2014 IEEE Geoscience and Remote Sensing Symposium, 2014Several papers highlighting the monotonic increase (with respect to wind speed) of the cross polarization radar backscatter (σ 0VH or VH for shorthand in the text) from the ocean surface have been published recently (Hwang et al, 2010a, b; Vachon and Wolfe, 2011; Zhang et al., 2011).

A radar backscatter model for discontinuous coniferous forests
IEEE Transactions on Geoscience and Remote Sensing, 1991A radar backscattering model for low-to-medium-density woodland in which each tree is treated as an individual backscatterer is described. A forest stand viewed by radar is then an assemblage of scatterers standing on a background in a certain spatial pattern.

Journal of Atmospheric and Terrestrial Physics, 1985
Abstract This paper provides an overview of six poster presentations contributed to the Open Symposium on Active Experiments in Space Plasmas at the XXIst General Assembly of URSI. The six poster presentations deal with HF ionospheric modification and are primarily experimental in nature.

Estimating splash pine biomass using radar backscatter
IEEE Transactions on Geoscience and Remote Sensing, 1991L-band HV multiple-incidence-angle aircraft synthetic aperture radar (SAR) data were analyzed in relation to average stand biomass, basal area, and tree height for 55 slash pine plantations located in northern Florida. This information was used to develop a system of equations to predict average stand biomass as a function of L-band (24.5-cm) radar ...
