Dependence of radar backscatter on coniferous forest biomass

IEEE Transactions on Geoscience and Remote Sensing, 1992
Two independent experimental efforts have examined the dependence of radar backscatter on above-ground biomass of monospecie conifer forests using polarimetric airborne SAR data at P-, L- and C-bands. Plantations of maritime pines near Landes, France, range in age from 8 to 46 years with above-ground biomass between 5 and 105 tons/ha.

Radar Backscatter Mapping Using TerraSAR-X

IEEE Transactions on Geoscience and Remote Sensing, 2011
Global backscatter data can be used for accurate synthetic aperture radar (SAR) performance estimation and optimizing instrument settings for SAR systems, e.g. the TerraSAR-X mission (TSM) and the TanDEM-X mission (TDM). The goal of this work is the generation of X-band backscatter maps by mosaicking images acquired by the TSM. An algorithm that allows

Radar-enabled backscatter communication

2022 56th Asilomar Conference on Signals, Systems, and Computers, 2022
In this work, we propose to use the echoes generated by a radar as a carrier waveform to establish and sustain a communication link between an ambient backscatter transmitter (tag) and a destination node (reader): we refer to this novel architecture as radar-enabled backscatter communication.
