caption_attribution_description: English: This image depicts the signal received from a CODAR source, centered on approximately 14195 kHz, on a software-defined radio's waterfall display. The CODAR signal is the repeating, sweeping, top left-to-bottom right signal. The bright signals to the right are unrelated.
context_page_description: Coastal ocean dynamics applications radar describes a type of portable, land-based, High Frequency radar developed between 1973 and 1983 at NOAA's Wave Propagation Laboratory in Boulder, Colorado. CODAR is a noninvasive system that permits to measure and map near-surface ocean currents in coastal waters. It is transportable and offers output ocean current maps on site in near real time. Moreover, using CODAR it is possible to measure waves heights and it provides an indirect estimate of local wind direction.
