THE HIGH FREQUENCY SURFACE WAVE RADAR SOLUTION FOR VESSEL TRACKING BEYOND THE HORIZON [PDF]

open access: yes, 2019
With maximum range of about 200 nautical miles (approx. 370 km) High Frequency Surface Wave Radars (HFSWR) provide unique capability for vessel detection far beyond the horizon without utilization of any moving platforms.

Propagation modeling and path loss prediction tools for high frequency surface wave radars [PDF]

open access: yes, 2010
Propagation modeling and simulation approaches for the use of High Frequency Surface Wave Radar (HFSWR) are discussed. HFSWR uses vertically polarized surface waves along multi-mixed paths in the lower HF band (3 MHz - 15 MHz).

Adaptive Waveform Design and CFAR Processing for High Frequency Surface Wave Radar [PDF]

open access: yes, 2017
High frequency surface wave radar (HFSWR), used for coastal surveillance, operates in a challenging environment as the clutter signals returned from the ocean surface can be several orders of magnitude larger than returns from targets. Reliably detecting

Radio frequency interference cancellation for sea-state remote sensing by high-frequency radar

open access: yes, 2011
High-frequency surface wave radar (HFSWR) has been widely adopted as a useful remote-sensing tool for sea-state monitoring. There are limitations to the performance because of various unwanted clutters and interferences that contaminate radar signals ...

Generalised noise cancellation method for wave estimation by HF surface wave radar

open access: yes, 2014
High frequency (HF) surface wave radar (HFSWR) has been demonstrated, in many experiments and papers, to be a powerful tool for sea-state detection. However, the availability and accuracy of the HFSWR measurements are limited by various unwanted clutter ...
