Improved Main Lobe Cancellation Method for Suppression Directional Noise in HFSWR Systems
High frequency surface wave radar (HFSWR) has been successfully developed for early warning, especially for vessel target detection. However, the system’s performance is consistently constrained by external environmental noise, particularly ...

Analysis and Estimation of Shipborne HFSWR Target Parameters Under the Influence of Platform Motion
IEEE Transactions on Geoscience and Remote Sensing, 2021For onshore high-frequency surface-wave radar (HFSWR), target parameter estimation focuses mainly on distance and velocity demodulation, then on azimuth determination. However, these parameters are difficult to solve accurately for shipborne HFSWR targets due to additional modulation on the echo signal introduced by the forward and six-degree-of ...

An Improved Oblique Projection Method for Sea Clutter Suppression in Shipborne HFSWR
IEEE Geoscience and Remote Sensing Letters, 2016Sea clutter has a major impact on the detection performance of a shipborne high-frequency surface wave radar (HFSWR) system. Due to the platform motion of shipborne HFSWR, the Doppler spectrum of the first-order sea clutter suffers from some broadening so that the targets submerged in this broadening Doppler spectrum can be hardly detected.

Simulation Analysis of First Order Sea Clutter Spectrum for Shipborne Bistatic HFSWR
IET Conference Proceedings, 2021Compared with onshore bistatic high frequency surface wave radar (BHFSWR) and shipborne monostatic HFSWR (MHFSWR), shipborne BHFSWR combines the common advantages of both. It is worth noting that the motion state of both mobile stations needs to be considered. In this paper, the spreading characteristics of first-order sea clutter and the doppler shift

Second-Order Ocean Surface Cross Section for Shipborne HFSWR
IEEE Antennas and Wireless Propagation Letters, 2015To 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 ...

Target Detection and Estimation for Shipborne HFSWR Based on Oblique Projection
2012 IEEE 11th International Conference on Signal Processing, 2012It is difficult to detect the target submerged in the spread spectrum of the first-order sea clutter caused by the platform motion in shipborne high frequency surface wave radar (HFSWR). Based on oblique projection operators with steering vector, a technique for the target detection in the spread clutter spectrum is proposed in this paper, which can ...
