High-Frequency Surface-Wave (HFSW) radars are a category of radars that operate at the frequency band 3-30 MHz and, in contrast with other radars, use ground wave or sky wave propagation and ionospheric reflections of the electromagnetic waves for target detection, which allows for achieving longer ranges, where microwave radars cannot perform [1], but to the detriment of the attained accuracy.
Furthermore, low-power HF surface-wave (HFSW) radars have demonstrated being a cost-effective long-range early-warning sensor for ship detection and tracking [22,23].
The OTH radar data used for the setting and evaluation of the presented work was acquired by the HFSW STRADIVARiUs radar by Diginext [33].
