A New Generation of HF Surface Wave Radar

open access: yes2025 IEEE Radar Conference (RadarConf25)
International audienceA primary function of a radar is to monitor a given area. For surface radars, the monitored area is limited by the horizon due to the Earth's curvature. To overcome this limitation, several concepts of HF Over The Horizon Radar (OTH-

Investigations with SECAR - a bistatic HF surface wave radar

2003 Proceedings of the International Conference on Radar (IEEE Cat. No.03EX695), 2004
This paper describes a bistatic HF surface wave radar, designated SECAR, which was deployed near Darwin, Australia, and used to conduct a variety of scientific investigations related to radar design, siting and target detection, as well as providing a test-bed for evaluating the operational utility of HFSWR as an element of a national surveillance ...

HF radar: surface wave and hybrid modes

2018 IEEE Conference on Antenna Measurements & Applications (CAMA), 2018
The object of this paper is the development of a HF radar simulator. The different modules which compose this simulator are described. Both the surface wave and the sky wave modes radiated by the HF antenna are considered.

Wave-Height Map Extraction From Compact HF Surface-Wave Radar Network

IEEE Geoscience and Remote Sensing Letters, 2021
The ocean-wave-height-measurement accuracy and coverage of high-frequency (HF) radars are affected by the echo intensity. Due to the effects of propagation attenuation and the wind-direction spreading function, the same sea area will generate different echo intensities for radars at different locations.

Correlation detector for HF surface wave radar

IET International Conference on Radar Systems (Radar 2012), 2012
Using empirical oceanographic knowledge a new detector is proposed which uses the property that azimuth variation of received power for a Range Doppler (RD) cell including a target will be more correlated across the adjacent RD cells as compared to a RD cell without a target.

HF surface wave radar simulation

IEE Colloquium on Radar System Modelling, 1998
One of the aims of radar performance modelling is to assess a radar's capability to fulfil its intended mission. This may be achieved by the simulation of all aspects of the radar's operation including target behaviour, environmental conditions, radar characteristics, and the radar/operator interface.

The case for bistatic HF surface wave radar

2008 International Conference on Radar, 2008
This paper examines some of the issues associated with implementation of HF surface wave radars (HFSWR) in bistatic and monostatic configurations. Most HFSWRs deployed in the field are pseudo-monostatic although they may not be optimum for all deployments.

Sea clutter canceller for shipborne HF Surface Wave Radar

2011 International ITG Workshop on Smart Antennas, 2011
A new type of beamformer has been proposed which uses dynamic clutter cancellation with the help of an auxiliary beam in an external clutter limited scenario like shipborne HF Surface Wave Radar (SWR). The beamformer is compact, ensures reasonable azimuth resolution and unlike the conventional beamformers the azimuth resolution decays gracefully in low

Experimental Evaluation of the Range–Doppler Coupling on HF Surface Wave Radars

IEEE Geoscience and Remote Sensing Letters, 2013
High-frequency surface wave radar (HFSWR) is used in oceanography to monitor surface wind waves and currents and, more recently, to detect ships in maritime surveillance. The radar accuracy is affected by range-Doppler coupling, which yields a displacement in the measured range proportional to the target radial velocity, i.e., the Doppler shift in the ...
