Analysis of sea spikes in radar sea clutter data

IEEE Transactions on Geoscience and Remote Sensing, 2006
In this paper three sets of high-resolution, coherent, and polarimetric radar sea clutter data are analyzed and compared with radar sea clutter models. The nature of the data allows a thorough analysis of the power, polarization and velocity of the sea clutter.

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.

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 ...

A New Way to Model Nonstationary Sea Clutter

IEEE Signal Processing Letters, 2009
Sea 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

Chaotic dynamics of sea clutter

Chaos: An Interdisciplinary Journal of Nonlinear Science, 1997
The 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, 2002
We 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 ...

An Analysis of Bistatic Sea Clutter Statistics

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
This 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.

Fractal approach for sea clutter generation

IEE Proceedings - Radar, Sonar and Navigation, 2000
Clutter 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.

Design and evaluation of a sea clutter simulator

2011 IEEE International Geoscience and Remote Sensing Symposium, 2011
This 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.
