Monitoring plant health using remote sensing: Advances and challengesMonitoramento Fitossanitário Utilizando Sensoriamento Remoto: Avanços e Desafios
(2021-04-01)
Problems concerning plant health, such as diseases, pests and weeds, which compete with grown plants for resources and, therefore, harm their full development, are responsible for significant losses in agriculture, year ...
Mapping Macrophyte Species in the Amazon Floodplain Wetlands Using Fully Polarimetric ALOS/PALSAR Data
(Institute of Electrical and Electronics Engineers (IEEE), 2011-12-01)
The purpose of this paper was to evaluate attributes derived from fully polarimetric PALSAR data to discriminate and map macrophyte species in the Amazon floodplain wetlands. Fieldwork was carried out almost simultaneously ...

Speckle noise and soil heterogeneities as error sources in a Bayesian soil moisture retrieval scheme for SAR data
(Institute of Electrical and Electronics Engineers, 2012-06)
—Soil moisture retrieval from SAR images is always affected by speckle noise and uncertainties associated to soil parameters, which impact negatively on the accuracy of soil moisture estimates. In this paper a soil moisture ...
Synthetic Aperture Radar (SAR) image processing for operational space-based agriculture mapping
(Taylor & Francis Ltd, 2020-09)
Few countries are using space-based Synthetic Aperture Radar (SAR) to operationally produce national-scale maps of their agricultural landscapes. For the past ten years, Canada has integrated C-band SAR with optical satellite ...
Mesoscale variability in the Alboran Sea: Synthetic aperture radar imaging of frontal eddies
(Journal of Geophysical Research, 2002)
In autumn 1992 the entire Alboran Sea (western Mediterranean) was sampled by the Spanish R/V García del Cid. The incoming jet of Atlantic water, its associated meandering front, and the two big anticyclonic gyres were ...
Optimal Canny's Parameters Regressions for Coastal Line Detection in Satellite-Based SAR Images
(Institute of Electrical and Electronics Engineers, 2020-01)
Canny's algorithm is a very well-known and widely implemented multistage edge detector. The extraction of coastal lines in space-borne-based synthetic aperture radar (SAR) images using this algorithm is particularly ...
