Analysis of sea spikes in radar sea clutter data

open access: yesIEEE 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 ...

Doppler characteristics of sea clutter. [PDF]

open access: yes, 2010
Doppler radars can distinguish targets from clutter if the target's velocity along the radar line of sight is beyond that of the clutter. Some targets of interest may have a Doppler shift similar to that of clutter. The nature of sea clutter is different

Chaotic modelling of sea clutter

open access: yesElectronics Letters, 1992
In the letter we present calculations based on experimental radar data which confirm the chaotic nature of sea clutter. In particular, the results of the calculations show that the first Lyapunov exponent of sea clutter is indeed positive and around 0 ...

Small target detection in sea clutter

open access: yesIEEE 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 ...

NetRAD multistatic sea clutter database

open access: yes2012 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.

Sea Clutter Amplitude Prediction Using a Long Short-Term Memory Neural Network

open access: yesRemote 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.

Modeling the Amplitude Distribution of Radar Sea Clutter [PDF]

open access: yesRemote Sensing, 2019
Ship detection in the maritime domain is best performed with radar due to its ability to surveil wide areas and operate in almost any weather condition or time of day. Many common detection schemes require an accurate model of the amplitude distribution of radar echoes backscattered by the ocean surface. This paper presents a review of select amplitude

Modelling of sea clutter with gaussian mixtures and estimation of the clutter parameter

open access: yesProceedings of the IEEE 12th Signal Processing and Communications Applications Conference, 2004., 2004
In order to model sea clutter, we propose to use a generalized distribution which is valid for different background statistics, like low and high sea states. The envelope detector's input statistics are assumed to be a Gaussian-mixture (GM). A new background probability density function (pdf) resembles Rician mixtures.

Nonlinear Dynamics of Sea Clutter [PDF]

open access: yesInternational Journal of Navigation and Observation, 2008
We review experimental evidence for the nonlinearity of sea clutter and the role of the z‐parameter or Mann‐Whitney rank‐sum statistic in quantifying this nonlinear behavior in the context of a hybrid AM/FM model for sea clutter, viewed as a cyclostationary process. An independent theoretical derivation of the stochastic dynamics of radar scattering in

Statistical analysis of bistatic and monostatic sea clutter

open access: yesIEEE Transactions on Aerospace and Electronic Systems, 2015
In this work, we analyze the sea clutter data collected simultaneously by the bistatic and monostatic nodes of an S-band netted radar system under different out-of-plane geometries. The empirical distribution of sea clutter data are fitted to some known heavy-tailed distributions, and the sea spikes statistics are examined.
