Leveraging the next generation of spaceborne Earth observations for fuel monitoring and wildland fire management

Remote Sensing in Ecology and Conservation, EarlyView.
This paper presents an interdisciplinary perspective of the next generation of spaceborne remote sensors applied to wildland fire management. We highlight the potential improvements in fuel characterization at large scale arising from the use of new spaceborne instruments with near‐global, freely‐available data.

Back projection algorithm-based GEO SAR real-time quick Look imaging system

The Journal of Engineering, 2019
Geosynchronous earth orbit synthetic aperture radar (GEO SAR) has the advantages of short revisit period and wide observation range. However, compared with low earth orbit SAR (LEO SAR), GEO SAR has the distinct characteristics of long synthetic aperture

Illuminating the Arctic: Unveiling seabird responses to artificial light during polar darkness through citizen science and remote sensing

Remote Sensing in Ecology and Conservation, EarlyView.
Artificial light at night (ALAN) has global impacts on animals, yet its effects in polar regions remain underexplored. In this study, we analyzed a decade of citizen science data on seabird occurrences in Longyearbyen, using remote sensing data to assess the impact of ALAN during the polar night.

Mapping oil palm plantations and their implications on forest and great ape habitat loss in Central Africa

Remote Sensing in Ecology and Conservation, EarlyView.
This paper takes a retrospective look at the changes in the extent of the Congo forest and great ape habitat in the past 20 years. The data and method used in this study are novel. This produced the very first Central Africa ‐specific oil palm extent and forest change dynamics, highlighting a great ape habitat and species range decline.

Advancing the mapping of vegetation structure in savannas using Sentinel‐1 imagery

Remote Sensing in Ecology and Conservation, EarlyView.
As vegetation structure monitoring is important for the understanding and conservation of savanna ecosystems, we explored the utility of C‐band synthetic aperture radar imagery for mapping both grassland and woody vegetation structure in the Greater Serengeti‐Mara Ecosystem.

Micro-Motion Estimation of Maritime Targets Using Pixel Tracking in Cosmo-Skymed Synthetic Aperture Radar Data—An Operative Assessment

Remote Sensing, 2019
In this paper, we propose a novel strategy to estimate the micro-motion (m-m) of ships from synthetic aperture radar (SAR) images. To this end, observe that the problem of motion and m-m detection of targets is usually solved using synthetic aperture ...
