Enhanced CNN-Based Small Target Detection in Sea Clutter With Controllable False Alarm
IEEE Sensors Journal, 2023As targets floating on the sea surface get more invisible, it is becoming vital and challenging to effectively detect small targets from strong sea clutter.

CA-CFAR Performance in K-Distributed Sea Clutter With Fully Correlated Texture
IEEE Geoscience and Remote Sensing Letters, 2023Sea clutter has been a long-standing issue in old and modern radars. Under this context, the K-distribution has emerged as a promising clutter model to accurately mimic sea signal variations in a large variety of radar systems.

IEEE Transactions on Aerospace and Electronic Systems, 2023
In this article, a novel range ambiguous cluter suppression method, i.e., alternating azitmuth phase coding (AAPC), based on azimuth phase coding (APC) is proposed, where the blind areas of target detection are solved.

Adaptive Persymmetric Detection for Radar Targets in Correlated CG-LN Sea Clutter
IEEE Transactions on Geoscience and Remote Sensing, 2023This article deals with the detection problem of a moving point-like target in correlated non-Gaussian sea clutter, which is modeled by a compound Gaussian model with a lognormal-distributed texture and an unknown covariance matrix.

Chaotic dynamics of sea clutter
Chaos: An Interdisciplinary Journal of Nonlinear Science, 1997The notion that a deterministic nonlinear dynamical system (with relatively few degrees of freedom) can display aperiodic behavior has a strong bearing on sea clutter characterization: random-looking sea clutter may be the outcome of a chaotic process. This new approach envisages deterministic rules for the underlying sea clutter dynamics, in contrast ...
