Ship Monitoring With Bistatic Compact HFSWR of Small Aperture
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022 High-frequency surface wave radar (HFSWR) can detect and continuously track ship targets in real time and beyond the horizon. Compared with transmit/receive (T/R) monostatic HFSWR, the T-R bistatic HFSWR has the advantages of flexibility ...

Sea Clutter Suppression Method of HFSWR Based on RBF Neural Network Model Optimized by Improved GWO Algorithm. [PDF]
Comput Intell Neurosci, 2020 The detection performance of high‐frequency surface‐wave radar (HFSWR) is closely related to the suppression effect of sea clutter. To effectively suppress sea clutter, a sea clutter suppression method based on radial basis function neural network (RBFNN) optimized by improved gray wolf optimization (IGWO) algorithm is proposed.

IET Radar, Sonar &Navigation, Volume 17, Issue 11, Page 1639-1645, November 2023., 2023 The authors proposes a new real‐time method to estimate the significant wave height directly from the antenna's received electric field in the time‐domain without requiring prior knowledge of the motion parameters or performing motion compensation. The results from this simple proposed technique show that it may be used to estimate the significant wave

IET Radar, Sonar &Navigation, Volume 17, Issue 10, Page 1498-1506, October 2023., 2023 Based on the time difference direction‐finding algorithm, new mathematical expressions of geometric dilution of precision (GDOP) are presented in Time Difference of Arrival positioning systems in this paper. The time difference direction‐finding reveals that the angle measurements are accurate for any length of baseline.

A novel sea clutter suppression method based on SVD‐FRFT at low signal‐to‐clutter ratio
Electronics Letters, Volume 59, Issue 14, July 2023., 2023 The target and sea clutter Doppler domains frequently overlap due to the frequent passage of slow ship targets through the sea clutter zone. In this letter, a novel sea clutter suppression method is suggested as a solution to this issue, whose key is a novel singular value zeroing criterion guided by the search results of two‐dimensional spectral peaks.
