   Recording of CONDAR transmissions on 4.630mhz. Coastal ocean dynamics applications radar ( CODAR) is a type of portable, land-based, high frequency (HF) radar developed between 1973 and 1983 at NOAA 's Wave Propagation Laboratory in Boulder, Colorado. CODAR is a noninvasive system that can measure and map near-surface ocean currents in coastal ...

3. Automatic identification system - Wikipedia

   en.wikipedia.org/.../Automatic_identification_system

   The automatic identification system ( AIS) is an automatic tracking system that uses transceivers on ships and is used by vessel traffic services (VTS). When satellites are used to receive AIS signatures, the term Satellite-AIS (S-AIS) is used. AIS information supplements marine radar, which continues to be the primary method of collision ...

4. Marine radar - Wikipedia

   en.wikipedia.org/wiki/Marine_radar

   Marine radars are X band or S band radars on ships, used to detect other ships and land obstacles, to provide bearing and distance for collision avoidance and navigation at sea. They are electronic navigation instruments that use a rotating antenna to sweep a narrow beam of microwaves around the water surface surrounding the ship to the horizon ...

   PAVE PAWS ( PAVE Phased Array Warning System) is a complex Cold War early warning radar and computer system developed in 1980 to "detect and characterize a sea-launched ballistic missile attack against the United States". [1]

7. Radar navigation - Wikipedia

   en.wikipedia.org/wiki/Radar_navigation

   Radar navigation. Radar ranges and bearings can be very useful for navigation. Radar navigation is the utilization of marine and aviation radar systems for vessel and aircraft navigation. When a craft is within radar range of land or special radar aids to navigation, the navigator can take distances and angular bearings to charted objects and ...
