Surface-wave over-the-horizon (OTH) radar is based on the diffraction of HF-radio waves propagated over the sea surface. This can be used for OTH surveillance of aircraft, surface ships and other surface objects as well as for carrying out remote sensing of sea-surface conditions in oceanographic, meteorological and ecological research [1].
The results of experiments show that in comparison with Fourier methods, the usage of the projective approach enables one to obtain double angular and frequency resolution, to reduce twice the time of detection of surface ships and aircraft, and to increase by 10...15 dB the dynamic range on the sidelobe level without lowering radar resolution.
