Modeling and Simulation of Coherent Sea Clutter
IEEE Transactions on Aerospace and Electronic Systems, 2012This paper describes a new technique for modeling and simulating the coherent returns from radar sea clutter, based on the compound K-distribution model for clutter amplitude statistics. Using observations of recorded Doppler spectra, a simple method is proposed for characterizing the temporal variations of the Doppler spectrum observed in a single ...

Analysis of multifractality for sea clutter
Proceedings of 2011 IEEE CIE International Conference on Radar, 2011To further research the multifractality of sea clutter, multifractality of IPIX radar sea clutter has been analyzed by Qth-order Moment Structure Partiction Function (Q-MSPF) method in detail in this paper, through simulation analysis, two target detection methods based on analysis of the mass exponent function and the source of multifractality are ...

Multifractal features of sea clutter
Proceedings of the 2002 IEEE Radar Conference (IEEE Cat. No.02CH37322), 2003Sea clutter refers to the backscattered returns from a patch of the sea surface illuminated by a transmitted radar pulse. Since the complicated sea clutter signals depend on the complex wave motions an the sea surface, it is reasonable to study sea clutter from nonlinear dynamics, especially chaos, point of view, instead of simply based on random ...

IEEE Transactions on Antennas and Propagation, 1968
First-order (small roughness amplitude) scattering theory is applied to obtain sea clutter cross sections in terms of mean-squared height spectrum of the sea surface. The results are in remarkably good agreement with observations for vertical polarization at P-, L-, C- , and X -bands.

Object detection in infrared image with sea clutter
The 6th International Conference on Soft Computing and Intelligent Systems, and The 13th International Symposium on Advanced Intelligence Systems, 2012In this paper, a new method for detecting various objects that can be risks to safety navigation in sea environment is proposed. By analyzing Infrared(IR) images obtained from various sea environments, we could find out that object regions include both horizontal and vertical direction edges while background regions of sea surface mainly include ...

Chaotic detection of small target in sea clutter
IEEE International Conference on Acoustics Speech and Signal Processing, 1993A new method based on chaos and neural network theory for small target detection in sea clutter is presented. The authors present the signal model. They then describe a neural network trained with the least-mean-square (LMS) algorithm for the dynamic reconstruction of sea clutter.

Sea clutter contamination test with log-cumulants
SPIE Proceedings, 2012In maritime applications involving estimation of radar sea clutter properties, non-sea-clutter targets and transitions between statistically different oceanographic conditions in the estimation window may lead to inaccurate modeling. Referring to mixtures in the estimation window as contamination, this work introduces a novel sea clutter contamination ...

AR-based growler detection in sea clutter
IEEE Transactions on Signal Processing, 1993A technique that performs better than conventional, noncoherent marine radars in detecting small pieces of glacial ice (growlers) in the sea is reported. A coherent detector based on an autoregressive (AR) parameterization of received radar echoes that distinguishes growler returns from the background sea clutter returns is considered.

Target Detection for Heterogeneous Cyclostationary Sea Clutter
Circuits, Systems, and Signal Processing, 2013This paper mainly deals with the problem of target detection under the heterogeneous background of cyclostationary sea clutter. Conventional approaches generally assume the ideal condition requiring the secondary data to be homogeneous with the primary data in order to exactly estimate the clutter covariance matrix and implement the adaptive filters ...

Prediction of radar sea clutter based on LSTM
Journal of Ambient Intelligence and Humanized Computing, 2019Radar sea clutter is the backscattering radar echo of rough sea surface, the research of radar sea clutter is of great significance to national defense construction and national economic development. Sea clutter prediction is also an important point in radar signal processing field. The traditional sea clutter prediction method has lower precision when
