Evaluation of the CODAR Tsunami Detection Algorithm and Software
OCEANS 2019 MTS/IEEE SEATTLE, 2019Coastal hazards pose a threat to human life and property around the globe. Tsunami waves and storm surge are some examples of coastal hazards we must try to mitigate over the coming decades. High Frequency radars have emerged as possible technology capable of mitigating the destruction from these hazards by providing early detection of these ...

CodAR: An Augmented Reality Based Game to Teach Programming
International Conference on Computers in Education, 2019In recent years, technology has revolutionized all spheres of life. Since programming is the heart of software technology, it is thus imperative that the demand for programmers is also increasing day by day. With advancements in the field of augmented reality (AR) and Computer Vision (CV), we can now develop applications for unique experiences in the ...

Correcting for distorted antenna patterns in CODAR ocean surface measurements
IEEE Journal of Oceanic Engineering, 1986CODAR systems employ compact antenna elements such as electrically small loops and monopoles to extract bearing information in ocean surface observations. Past analysis methods have assumed that these element patterns are perfect, i.e., cosine and omnidirectional.

CODAR measurements of ocean surface parameters at ARSLOE--Preliminary results
OCEANS 82, 1982We here report on a preliminary analysis of data taken by a coastal HF radar system (CODAR) which was operated during the ARSLOE experiment. The system produces the first five Fourier coefficients of the directional ocean waveheight spectrum and two-dimensional maps of radial surface current velocity.

Detection of Ships with Multi-Frequency and CODAR SeaSonde HF Radar Systems
Canadian Journal of Remote Sensing, 2001 RESUMELes systemes CODAR Seasonde et MCR (Multi-Frequency Coastal Radar) sont concus pour mesurer les caracteristiques environnementales oceaniques, en particulier les courants oceaniques, les vagues et les vents. En plus de permettre ces mesures, ces systemes ont aussi la capacite de detecter des cibles discretes comme les navires.

Coastal Ocean Dynamics Radar (CODAR): NOAA's Surface Current Mapping System
OCEANS '79, 1979NOAA has developed a shore-based HF radar system that maps ocean surface currents out to 60 km from shore. Currents are derived from the Doppler shift of radar echoes from 6-m ocean waves, whose phase speed is altered by underlying currents. A map containing 800 current vectors covering 2000 square kilometers of ocean can be produced automatically in ...

Tidal and storm-surge measurements with single-site CODAR
IEEE Journal of Oceanic Engineering, 1986In this paper we describe the results of a detailed analysis of CODAR measurements made from a single site during the Atlantic Remote Sensing Land Ocean Experiment (ARSLOE). The passage of a storm front generated a surge followed by wind and current reversal, superimposed on the normal semi-diurnal tides.

2008 IEEE/OES 9th Working Conference on Current Measurement Technology, 2008
The year 1978 saw the first of these CMTC meetings, at Newark, DE. At that initial symposium, CODAR was introduced to the current measurement community. The word CODAR had been coined by the author at NOAA two years earlier, to describe a novel HF radar technique that now routinely maps surface currents from hundreds of coastal sites in real time. This

Identifying ship echoes in CODAR HF radar data: A Kalman filtering approach
OCEANS 2010 MTS/IEEE SEATTLE, 2010Coastal nations have an interest in maritime domain awareness for applications in national security, coastal conservancy, fishery and stewardship of the exclusive economic zones (EEZs) along their coastlines. Maritime situational awareness involves knowing the location, speed and bearing of ships and boats in the EEZ.

Simultaneous CODAR and OSCR measurements of ocean surface currents in Monterey Bay
IGARSS '96. 1996 International Geoscience and Remote Sensing Symposium, 2005Presently, three Coastal Ocean Dynamics Applications Radars, or CODARs, which are ocean surface current measuring radars, are operated around Monterey Bay, California and provide data hourly to an ONR-funded real time environmental monitoring system operated through UC Santa Cruz known as REINAS. CODARs operate using Bragg scatter of high frequency (HF)
