HF RADAR 25kHz CODAR Long Range | Signal Phantom

These 25 kHz HF RADAR stepped pulse sweeps use FMCW or ILFM (Interpulse Linear Frequency Modulation) modulation and are part of the CODAR (Coastal Ocean Dynamics Applications Radar) project by Don Barrick to obtain ocean wave and surface current monitoring using Bragg scatter. The SeaSonde sensors seen here are long range sensors (100 to 220kM) operating from 4.3 to 5.4 MHz (lower48) and operate at or under 80w PEP per license. The Coastal Observing Research and Development Center has mapping and data related to these sensors if you are interested in seeing the coastal sensor data.
