Littoral sea clutter returns at 94GHz [PDF]
2014 International Radar Conference, 2014 This paper reports and discusses measurements made of the returns from sea clutter in the littoral at 94GHz using the SAFIRE demonstration radar. These measurements add significantly to the limited data which is available on sea clutter at 94GHz as well as showing how a radar developed to assist the public understanding of technology can also be used ...

mRMR-Tri-ConcaveHull Detector for Floating Small Targets in Sea Clutter
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023 For the feature-based detector of small targets in sea clutter, on the one hand, the three-dimensional convex hull-based detector deviates from the distribution of sea clutter vectors in the feature space and only combines the information of low ...

Mitigation of the Effects of Unknown Sea Clutter Statistics by Using Radial Basis Function Network [PDF]
Radioengineering, 2020 In this paper, we investigate feasibility of employing Radial Basis Function (RBF) network into non-coherent detection process, for detection of targets embedded in sea clutter of unknown statistics. We particularly have in mind Croatian part of Adriatic

Infrared Small Marine Target Detection Based on Spatiotemporal Dynamics Analysis
Remote Sensing, 2023 It is a big challenge to detect and track small infrared marine targets in non-stationary and time-varying sea clutter because the signal is too strong to be estimated.
