LDA-MIG Detectors for Maritime Targets in Nonhomogeneous Sea Clutter

IEEE Transactions on Geoscience and Remote Sensing
This article deals with the problem of detecting maritime targets embedded in nonhomogeneous sea clutter, where the limited number of secondary data is available due to the heterogeneity of sea clutter. A class of linear discriminant analysis (LDA)-based

Small Target Detection in Sea Clutter by Weighted Biased Soft-Margin SVM Algorithm in Feature Spaces

IEEE Sensors Journal
Sea-surface small target detection in high-resolution sea clutter is always an intractable problem. Feature-based detection in multidimensional feature spaces is recognized to be an effective way, and therein, learning algorithms with controllable false ...

A PointNet-Based CFAR Detection Method for Radar Target Detection in Sea Clutter

IEEE Geoscience and Remote Sensing Letters
Radar target detection on the sea surface is challenging due to the influence of sea clutter. Traditional radar target detection methods cannot model the sea clutter distributions precisely, resulting in poor target detection performance. In this letter,

A Novel Data-Driven Modeling Method for the Spatial–Temporal Correlated Complex Sea Clutter

IEEE Transactions on Geoscience and Remote Sensing, 2022
The sea clutter, referred to as the time-varying radar backscatter from the ocean surface, plays a significant role in marine radar development. The ocean’s complex hydrodynamics cause it to exhibit non-Gaussian and nonstationary characteristics, which ...

NetRAD multistatic sea clutter database

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
This paper describes a multistatic, sea clutter and vessel database, assembled using the three node, S Band radar, known as NetRAD (for, “Netted Radar”). This data was collected in the United Kingdom and South Africa during 2009-201. It is the intention of the investigators and sponsors of this work to make the raw data available to individuals and ...

Efficient Matrix Sparse Recovery STAP Method Based on Kronecker Transform for BiSAR Sea Clutter Suppression

IEEE Transactions on Geoscience and Remote Sensing
Sea clutter suppression plays a crucial role in maritime moving target indication. However, in the bistatic synthetic aperture radar (BiSAR) system, traditional space-time adaptive processing (STAP) method cannot satisfy the expected performance due to ...

Wald- and Rao-Based Detection for Maritime Radar Targets in Sea Clutter With Lognormal Texture

IEEE Transactions on Geoscience and Remote Sensing, 2022
Non-Gaussian sea clutter causes conventional detectors designed in Gaussian clutter to suffer detection performance degradation, and some nuisance parameters cause the uniformly most powerful test to be unavailable.

Eigenvalues-Based Detector Design for Radar Small Floating Target Detection in Sea Clutter

IEEE Geoscience and Remote Sensing Letters, 2022
In this letter, the correlation structure inherent in the received data is exploited to improve detection performance for sea-surface small floating targets in short observation time. Three detectors are devised resorting to the eigenvalues of covariance
