Target Detection Using HF Radar Data
OCEANS 2007 - Europe, 2007High frequency (HF) radar systems have a potential to detect targets which are located beyond the optical horizon on the sea surface. Unfortunately sea clutter may be strong enough to prevent such detection. In this work we present results of applying space-time adaptive processing (STAP) to this problem.

7th International Conference on High Frequency Radio Systems and Techniques, 1997
HF radar groups working within separate organisations are likely to use different versions of the HF radar equation. When it is necessary to collaborate, or otherwise share know-how, there are fresh opportunities for misunderstanding. In this paper some alternative definitions of transmission loss, antenna gain and target backscattering cross-section ...

On the design of a 2D array HF skywave radar
2008 IEEE Radar Conference, 2008New generation of HF skywave radars moves toward 2D array solution to get high signal to noise ratio (SNR), low probability of intercept (LPI), precise electronic scanning, faster scanning time. Critical elements for the design of such a system are radar configuration, antenna design, transmission waveforms and architecture, signal processing, radar ...

A Novel Radar Waveform Design for a Low-Power HF Monostatic Radar
IEEE Geoscience and Remote Sensing Letters, 2015In this letter, a novel radar waveform is proposed for a low-power high-frequency monostatic radar used for ionospheric sensing and aircraft detection. In this proposed waveform, a hybrid modulation scheme is adopted, where the pulse-to-pulse phase is coded by the WG sequence, and the frequency of each subpulse is linearly modulated with a fixed chirp ...

The extraction of useful information from radar echoes cannot be accomplished solely within the domain of ‘direct’ problems, that is to say, the solution of Maxwell’s equations with prescribed boundary conditions. In general, the interpretation of radar returns involves the solution of inverse problems, which are essentially illposed, even in the ...

Guidelines on how to sync your High Frequency (HF) radar data with the European HF Radar node
2019A step-by-step guide to help High-Frequency (HF) radar data providers synchronize their near real-time native data files or standard NetCDF datasets to the European HF radar node and, from there, to other data distribution portals (Copernicus Marine Service, EMODnet-Phys and SeaDataNet)
