The first-order Bragg lines in ship borne high frequency surface wave radar (HFSWR) are spread due to the platform motion, and the space-time distribution of the first-order sea clutter manifests itself as two ideal diagonal lines. However, because of the interaction between platform and sea environment (such as ocean wave, current and wind), the first-order sea clutter spectra are influenced by the...
Land-based high frequency surface wave radar (HFSWR) has been successfully employed for early warning and ocean remote sensing. However, there remain potential gaps for shipborne HFSWR in the application of ocean remote sensing. In this paper, the feasibility of extracting wind direction is studied based on the first-order ocean surface cross section in shipborne HFSWR. According to the spreading...
To investigate the characteristics of sea clutter in monostatic shipborne high-frequency surface-wave radar (HFSWR) with uniform linear motion, the second-order patch scatter cross section is derived. With the previously proposed first-order ocean surface cross section, both cross sections could be reduced to the existing results in land-based HFSWR. Illustrations and discussions are provided on the...
