Multistatic networked radar for sea clutter measurements
2011 IEEE International Geoscience and Remote Sensing Symposium, 2011NetRad, consisting of three fully coherent S-Band (2400 MHz) nodes, synchronised by clock and trigger cables, or, GPS Disciplined Oscillators (GPSDOs) with a programmable trigger, has been underdevelopment at UCL and UCT for a number of years. Basic output power is low (200 mW), but a high power transmitter (500W peak) is available for one node.

The characteristics of radar sea clutter
2006In 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.

Properties of polarimetric sea clutter at 35 GHz
2007 IEEE International Geoscience and Remote Sensing Symposium, 2007The FGAN operated MEMPHIS radar was used to measure the backscatter behaviour of sea clutter at 35 GHz. The resulting fully polarimetric, carefully calibrated reflectivity data were analysed with respect to their temporal and spatial characteristics. Temporal decorrelation is fast, accordingly the polarimetric persistence is very low.

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 ...

On the Mechanisms of Radar Sea Clutter
Proceedings of the IRE, 1957Experimental 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.

Representation of radar sea clutter
IEE Proceedings F Communications, Radar and Signal Processing, 1988Sea 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.

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

Empirical models for sea clutter
2013The 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.

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.

Study and simulation of sea clutter
[1993 Proceedings] IEEE Signal Processing Workshop on Higher-Order Statistics, 2002Modeling 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.
