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
