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)

CODAR: General purpose design tool for rule-based engineering expert systems
Advanced Engineering Informatics, 1987Abstract CODAR is a software tool for the design of engineering expert systems. It combines both deductive reasoning and abductive reasoning with the inclusion of both thresholding and probability as uncertainty models. The system has explicit support of hypothesization.

CODAR Directional Biases with a Four-Element Antenna Array
IEEE Transactions on Geoscience and Remote Sensing, 1986Directional biases are shown to exist for a four-element square CODAR receiving array used for coastal current mapping. The sources being sidelobes and mutual coupling (a type of pattern distortion), these nonstatistical biases depend both on the geometry/size of the square array as well as the particular closed-form algorithm employed to estimate ...

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 ...

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.

Surface Currents During The ARSLOE Storm Measured By The CODAR Crossed-Loop System
Proceedings OCEANS '83, 1983Data from a single-site CODAR system were used to study near-shore surface currents during a storm at ARSLOE. The dominant surface currents resulted from the storm winds and waves; tidal currents observed were nearly an order of magnitude weaker. The onshore and alongshore current components changed direction when these components of the wind reversed.

Extraction of surface currents from first-order CODAR sea echo requires use of a model that allows signals from two bearings to contribute to the Doppler spectrum at a given frequency. This is called the dual-angle situation, and it applies over much of the coverage area.
