Small-target detection in sea clutter
IEEE Transactions on Geoscience and Remote Sensing, 2004 Sea clutter in marine surveillance radar makes the task of detecting small targets a very challenging problem. In this paper, a set of three signal processing techniques designed to suppress unwanted sea clutter radar echo and achieve target detection with no prior knowledge of the ocean and environmental conditions is presented.

A New Way to Model Nonstationary Sea Clutter
IEEE Signal Processing Letters, 2009Sea clutter refers to the radar backscatter from a patch of ocean surface. To properly characterize radar clutter returns, a lot of effort has been made to fit various distributions to the observed amplitude data of sea clutter. However, the fitting of real sea clutter data using those distributions is not satisfactory. This may be due to the fact that

, 2012 This dissertation presents the results of a study, the aim of which was the prediction of sea clutter characteristics including the temporal properties of the return signals as observed by a maritime surveillance radar system. The compound K distribution model used to generate clutter amplitude statistic enables the simulation of sea clutter with a ...

Sea Clutter Amplitude Prediction Using a Long Short-Term Memory Neural Network
Remote Sensing, 2019 In the marine environment, shore-based radars play an important role in military surveillance and sensing. Sea clutter is one of the main factors affecting the performance of shore-based radar.

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 ...

Analysis of sea clutter radar data
Proceedings of International Radar Conference, 2002We perform a detailed analysis of experimental data, collected at Osborne Gunnery Range with MacMaster University IPIX radar, to test the theoretical models developed in the literature. A comparison of the amplitude histograms with the K and lognormal distribution shows that VV data exhibit a K behaviour, while HH data are better fitted by a lognormal ...

Fractal approach for sea clutter generation
IEE Proceedings - Radar, Sonar and Navigation, 2000Clutter is obtained by applying physical optics to a sea surface described by a fractal model. This approach gives two interesting advantages. It is possible to control sea, radar and geometry parameters so reproducing a realistic scenario in which the clutter signal is generated.

An Analysis of Bistatic Sea Clutter Statistics
IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018This paper studies the amplitude distribution of bistatic sea clutter using a physics-based model. Such a study assists in understanding clutter statistics for target detection and remote sensing applications. The formulation of the model is based on a “two-scale” decomposition and Elfouhaily spectrum.

Design and evaluation of a sea clutter simulator
2011 IEEE International Geoscience and Remote Sensing Symposium, 2011This paper outlines the design of a sea clutter simulator based on the K distribution. Sea clutter is the radar backscattered return from the sea surface. Any radar operating in maritime environment must have the ability to compensate for this clutter effect to achieve effective target detection.

NetRAD multistatic sea clutter database
2012 IEEE International Geoscience and Remote Sensing Symposium, 2012This 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 ...
