Ocean Surface Cross Sections for Shipborne HFSWR With Sway Motion [PDF]
Radio Science, 2016 AbstractTo interpret the essential characteristics of the sea echo backscattered from the ocean surface, the first‐ and second‐order ocean surface cross sections are mathematically derived for an omnidirectional receiving sensor in monostatic shipborne high‐frequency surface wave radar (HFSWR), where the uniform linear motion and sway motion are ...

First-Order Ocean Surface Cross-Section for Shipborne HFSWR
Electronics Letters, 2013 Onshore high‐frequency surface wave radar (HFSWR) has been successfully deployed for early warning and ocean remote sensing. However, there remain potential gaps in ocean remote sensing for shipborne HFSWR. Based on the first‐order bistatic field equation, the first‐order ocean surface cross‐section for shipborne HFSWR is derived, whose validity is ...

Prediction cancellation method of sea clutter in shipborne HFSWR
Electronics Letters, 2016 Sea clutter has a serious influence on the detection performance of a shipborne high‐frequency surface wave radar (HFSWR) system, especially when the target is submerged in the spread Doppler spectrum of the first‐order sea clutter. A prediction cancellation (PC) method based on the radial basis function neural network (RBFNN) is put forward to ...
