Estimating Endmember Backscattering Coefficients Within the Mixed Pixels Based on the Microwave Backscattering Contribution Decomposition Model [PDF]
SensorsThe complexity of land types and the limited spatial resolution of Synthetic Aperture Radar (SAR) imagery have led to widespread mixed-pixel contamination in radar backscatter images.

94 GHz Radar Backscatter Characteristics of Alpine Glacier Ice
Geophysical Research Letters, 2023 Measuring the radar backscatter characteristics of glacier ice at different frequencies and incidence angles is fundamental to predicting the glacier mapping performance of a sensor. However, such measurements at 94 GHz do not exist.

Radar-Enabled Ambient Backscatter Communications
IEEE Transactions on Wireless Communications, 2023 In this work, we exploit the radar clutter (i.e., the ensemble of echoes generated by the terrain and/or the surrounding objects in response to the signal emitted by a radar transmitter) as a carrier signal to enable an ambient backscatter communication from a source (tag) to a destination (reader).

Wide-Area Analysis-Ready Radar Backscatter Composites [PDF]
IEEE Transactions on Geoscience and Remote Sensing, 2022 The benefits of composite products are well known to users of data from optical sensors: cloud-cleared composite reflectance or index products are commonly used as an analysis-ready data (ARD) layer. No analogous composite products are currently in widespread use that is based on spaceborne radar satellite backscatter signals.

Remote Sensing, 2023 The differential propagation phase (ΦDP) of X-band dual-polarization weather radar (including X-band dual-polarization phased-array weather radar, X-PAR) is important for estimating precipitation and classifying hydrometeors.

New Features of Bragg and Non-Polarized Radar Backscattering from Film Slicks on the Sea Surface
Journal of Marine Science and Engineering, 2022 Suppression of radar backscattering from the sea surface has been studied in field experiments with surfactant films carried out from an Oceanographic Platform on the Black Sea and from onboard a research vessel on the Gorky Water Reservoir using an X-C ...

A comparison of satellite scintillation measurements with HF radar backscatter characteristics [PDF]
Annales Geophysicae, 2005 We examine the correspondence between high latitude ionospheric scintillation measurements made at 250MHz with the occurrence of 10MHz HF coherent radar backscatter, on 13 and 14 December 2002.

Initial backscatter occurrence statistics from the CUTLASS HF radars [PDF]
Annales Geophysicae, 1997 A statistical study of the occurrence of ground and ionospheric backscatter within the fields-of-view of the CUTLASS HF radars, at an operating frequency of 10 MHz, during the first 20 months of operation has been undertaken.
