High Frequency (HF) Radar Detection of the Weak 2012 Indonesian Tsunamis

open access: yesRemote Sensing, 2012
We report here on the observation and offline detection of the weak tsunamis generated by earthquakes near Indonesia on 11 April 2012 using radar systems and tide gauges on the coasts of Sumatra and the Andaman Islands.

Enhanced-resolution reconstruction for the China-France Oceanography Satellite scatterometer

open access: yesGeocarto International, 2023
The China-France Oceanography Satellite SCATterometer (CSCAT) can observe radar backscatter values on the same sea surface at multiple incidence angles, and is often used to estimate the ocean near-surface wind.

Societal Applications of HF Skywave Radar

open access: yesRemote Sensing, 2022
After exploratory research in the 1950s, HF skywave ‘over-the-horizon’ radars (OTHR) were developed as operating systems in the 1960s for defence missions, notably the long-range detection of ballistic missiles, aircraft, and ships.

Remote Observation of a Small Meteotsunami in the Bight of Benin Using HF Radar Operating in Lower HF Band

open access: yesIEEE Access, 2019
High-frequency (HF) surface-wave (SW) radar systems have demonstrated their capability to capture the signals from seismic and non-seismic tsunami events using the estimation of surface current changes. Several ocean radar systems, operating in the upper

Satellite altimetry for Indian reservoirs

open access: yesWater Science and Engineering, 2021
Satellite radar altimetry has immense potential for monitoring fresh surface water resources and predicting the intra-seasonal, seasonal, and inter-annual variability of inundated surface water over large river basins.

A new airborne system for simultaneous high-resolution ocean vector current and wind mapping: first demonstration of the SeaSTAR mission concept in the macrotidal Iroise Sea [PDF]

open access: yesOcean Science
Coastal seas, shelf seas and marginal ice zones are dominated by small-scale ocean surface dynamic processes that play a vital role in the transport and exchange of climate-relevant properties such as carbon, heat, water and nutrients between land, ocean,

Coastal Oceanography Applications of Digital Image Data from Marine Radar

open access: yesJournal of Atmospheric and Oceanic Technology, 2000
A marine radar attached to a digital image capture system has been adapted for deployment from shore sites. Optimum operating parameters have been identified in relation to the resolution and sampling capabilities of both the radar and the digitization system.

Applications of Synthetic Aperture Radar to Meteorology and Oceanography Command Operations [PDF]

open access: yes, 2007
Abstract : Our long-term goal is to employ near-surface wind speed derived from synthetic aperture radar (SAR) images of the sea surface as a marine meteorological research and forecasting tool. That is, we aim to use SAR-derived wind speed (SDWS) images to discover dynamical and morphological characteristics of microscale, mesoscale, and synoptic ...
