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 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.

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.

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 ...

Ionospheric Clutter Suppression in HF Surface Wave Radar

Journal of Electromagnetic Waves and Applications, 2009
The ionospheric clutter has been proved to be one of the dominant clutters degrading the performance of the HF surface-wave radar (HFSWR) severely, so suppressing the ionospheric clutter is a vital part of radar signal processing sequence. In this paper, the spatial characteristics of the ionospheric clutter in a planar array are analyzed, then a new ...

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.

HF surface wave radar operation in adverse conditions

2003 Proceedings of the International Conference on Radar (IEEE Cat. No.03EX695), 2004
For the past 12 years the Canadian Department of National Defence and Raytheon Canada Limited have collaborated on a cost-shared programme to develop an Integrated Maritime Surveillance (IMS) system based on HF Surface Wave Radar (HFSWR). The primary objective behind the programme was to demonstrate the capability of HFSWR to continuously detect and ...

Improved correlation detector for HF Surface Wave Radar

2011 IEEE RadarCon (RADAR), 2011
The challenge in HF Surface Wave Radar (SWR) lies in the detection of a target signal in the background of a strong sea clutter. An improved detector is presented which uses the property that the cut of sea clutter power along the azimuth axis is correlated over neighboring Range Doppler cells.

Ship detection and tracking using HF surface wave radar

RADAR 2002, 2003
The Canadian Department of National Defence (DND) conducted a joint trial involving multiple sensors in the detection and tracking of ships in the Grand Banks of Canada in March 2000, including the HF surface wave radar (HFSWR) system at Cape Race, Newfoundland.

Surface wave HF radar simulator

Radar Systems (RADAR 97), 1997
A 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 ...
