New Spatial Correlation Models for Sea Clutter

IEEE Geoscience and Remote Sensing Letters, 2015
In this letter, new models for the spatial correlation of sea clutter texture and intensity are proposed as improved versions of current power law models or exponential decay model. The models for texture have three unknown parameters, and thus can be called triparametric models.

On the Mechanisms of Radar Sea Clutter

Proceedings of the IRE, 1957
Experimental data on radar sea clutter are described and discussed with reference to the physical principles involved. It is shown that the scattering elements are illuminated by a combination of direct and indirect fields, the latter being "reflected" by surface elements closer to the radar.

The characteristics of radar sea clutter

2006
In this chapter, sea clutter is described in terms of its observed characteristics. These observations will provide the foundations upon which the themes of subsequent chapters are developed. Radars operating in a maritime environment inevitably encounter backscattered radar signals from the sea surface, usually referred to as sea clutter.

Representation of radar sea clutter

IEE Proceedings F Communications, Radar and Signal Processing, 1988
Sea clutter data obtained with a land-based X-band radar are analysed in terms of a correlated gamma-distributed noise model. Results obtained with both vertical-vertical and horizontal–horizontal transmit-receive polarisations are shown to be broadly compatible with the model.

Multiscale modeling of sea clutter to facilitate detection of low observable targets within sea clutter

SPIE Proceedings, 2009
Sea clutter, the radar backscatter from the ocean surface, is highly complicated and non-stationary, due to multipath propagation of the radar returns and multiscale interactions at the air-sea interface. To facilitate robust detection of low observable targets within sea clutter, which is an important issue in coastal security, navigation safety and

Empirical models for sea clutter

2013
The observed characteristics of radar sea clutter were described in the previous chapter. This chapter presents some of the empirical models that describe sea clutter characteristics and that can be applied for signal processing design and radar performance predictions.

Study and simulation of sea clutter

[1993 Proceedings] IEEE Signal Processing Workshop on Higher-Order Statistics, 2002
Modeling sea clutter of high resolution maritime surveillance radar must provide a validation of algorithms in a perfect well-known context, before comparison with real data. The purpose of the paper is to study modelling of the sea clutter. It considers the temporal evolution of sea clutter for which statistical analysis is carried out.

Target Detection in Sea Clutter Based on ELM

2018
Target detection is a hot topic in the research of sea clutter. The solution of this problem can be divided into two aspects. Firstly, find out the different characteristics between the target and sea clutter. Secondly, take advantage of the classifier to realize the feature classification. Thus, we study the characteristics of sea clutter. As a result,

Statistical models of sea clutter

2006
In this chapter the authors develop the models of sea clutter that will provide a basis for our subsequent discussion and calculation of radar performance. As the authors saw in the previous chapter, a direct approach to the modelling of sea clutter provides many useful insights.
