A Bio-Optical Model Customized for Estimating Red Tide Intensity of
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingRemote sensing reflectance (Rrs) is a fundamental optical variable that characterizes the color of ocean water, which is governed by the composition of in-water constituents such as phytoplankton, suspended sediments, and colored dissolved organic matter.

A Low-Cost Active Reflector for Interferometric Monitoring Based on Sentinel-1 SAR Images
Sensors, 2021 The effectiveness of radar interferometric techniques in non-urban areas can often be compromised due to the lack of stable natural targets. This drawback can be partially compensated through the installation of reference targets, characterized by a ...

Simplifying Backscatter Deployment: Full-Duplex LoRa Backscatter
CoRR, 2020 Due to the practical challenges in the deployment of existing half-duplex systems, the promise of ubiquitous backscatter connectivity has eluded us. To address this, we design the first long-range full-duplex LoRa backscatter reader. We leverage existing LoRa chipsets as transceivers and use a microcontroller in combination with inexpensive passive ...

Backscattering differential ghost imaging in turbid media. [PDF]
Physical Review Letters, 2012 In this Letter we present experimental results concerning the retrieval of images of absorbing objects immersed in turbid media via differential ghost imaging (DGI) in a backscattering configuration. The method has been applied, for the first time to our

Underwater backscatter networking [PDF]
Proceedings of the ACM Special Interest Group on Data Communication, 2019 We present Piezo-Acoustic Backscatter (PAB), the first technology that enables backscatter networking in underwater environments. PAB relies on the piezoelectric effect to enable underwater communication and sensing at near-zero power. Its architecture is inspired by radio backscatter which works well in air but cannot work well underwater due to the ...

Backscattering peak of ice cloud particles.
Optics Express, 2015 At a wavelength corresponding to negligible electromagnetic absorption by ice, rigorous numerical simulations based on solving Maxwell's equations show a backscattering peak associated with the phase function of randomly oriented hexagonal ice crystals ...
