Sixth International Conference on `HF Radio Systems and Techniques', 1994
HF over-the-horizon radars often use CW transmissions comprising repeated linear FM sweeps. The resolution and sidelobe performance in the range dimension are determined within each sweep, but Doppler information is extracted by processing together the outputs of a number of sweeps.

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 ...

Workshop on Hf Radars for Coastal Oceanography
2001Abstract : The long-term goal is to begin an annual workshop series on HF radars that promotes and facilitates interactions among HF radar engineers, scientists and users and publishes new developments with the goal of making HF radars an acceptable and reliable tool for oceanographic applications.

Surface wave HF radar simulator
Radar Systems (RADAR 97), 1997A computer code is described which has been developed for the simulation of surface wave high frequency (SW-HF) radar. The aim is to investigate the problems related to the detection and tracking of surface targets at beyond the horizon ranges. In SW-HF radar target detection involves stochastic features such as target RCS fluctuations, atmospheric ...

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)
