Wind Turbine Clutter Mitigation in Coastal UHF Radar
The Scientific World Journal, 2014 Coastal UHF radar provides a unique capability to measure the sea surface dynamic parameters and detect small moving targets, by exploiting the low energy loss of electromagnetic waves propagating along the salty and good conducting ocean surface.

Investigations of the lower and middle atmosphere at the Arecibo Observatory and a description of the new VHF radar project [PDF]
, 1986 The atmospheric science research at the Arecibo Observatory is performed by means of (active) radar methods and (passive) optical methods. The active methods utilize the 430 NHz radar, the S-band radar on 2380 MHz, and a recently constructed Very High ...

Measuring Ocean Surface Waves Using HF Ground Wave Radar: Validation Against a Wave Model
Canadian Journal of Remote Sensing, 1993 RESUMEOn assiste actuellement a la naissance d'une nouvelle technique de teledetection qui permet de mesurer, de facon systematique, l'etat de la mer et les courants oceaniques de surface. Cette nouvelle technique s'appuie sur l'utilisation d'un radar hyperfrequence a ondes de sol (HFground wave radar).

HF Radar Sea-echo from Shallow Water
Sensors, 2008 HF radar systems are widely and routinely used for the measurement of ocean surface currents and waves. Analysis methods presently in use are based on the assumption of infinite water depth, and may therefore be inadequate close to shore where the radar ...

High-Speed Target Tracking Method for Compact HF Radar
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingCompact high-frequency (HF) surface wave radar can be used for remote sensing of sea surface dynamic parameters, such as winds, waves, and currents, as well as hard targets, such as ships and low-altitude aircrafts.
