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 ...

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 ...

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 ...

First order sea clutter cross section for bistatic shipborne HFSWR [PDF]
Journal of Systems Engineering and Electronics, 2017 This paper studies the development on the first order sea clutter cross section for bistatic high frequency surface wave radar (HFSWR). Based on the received first order electric field expression, a closed-form of cross sections is derived to account for the case of receiving antenna array being mounted on the shipborne platform.

Sea clutter suppression for shipborne HFSWR using joint sparse recovery‐based STAP [PDF]
Electronics Letters, 2016 On the basis of the intrinsic sparsity of sea clutter in shipborne high‐frequency surface wave radar, a joint sparse recovery‐based space–time adaptive processing (STAP) technique is proposed to suppress the spread sea clutter. In the proposed method, the partial clutter subspace is first estimated with training samples from only one range cell ...

IET Radar, Sonar & Navigation, 2018 To investigate the characteristic of ocean surface backscatter echo, the first‐order ocean surface cross‐section for shipborne high‐frequency surface wave radar (HFSWR) incorporating a horizontal oscillation motion model is mathematically derived. The horizontal oscillation motion includes yaw, sway and surge.
