Depending on radar parameters and sea surface conditions, each component of the received sea-clutter may be correlated and appropriate correlation models should be included in the simulation. For K-distributed sea-clutter, methods for simulating both correlated Gaussian and . Modelling and simulation of the sea-clutter characteristics allows analysis of a wider set of possible geometries and sea-conditions. Large body of literature on sea-clutter analysis and modelling. Mostly from coarse resolution radars at low grazing angles.

  In her second book, author Eve Schaub explored the tendencies to accumulate too much stuff in her humorous and engaging memoir “Year of No Clutter”. This book follows her debut release: “Year of No Sugar” (). Included is a quote by Anne Lamott: “Nothing heals us like letting people know our scariest parts.”/5(). CHAPTER 13 SEA CLUTTER Lewis B. Wetzel Naval Research Laboratory INTRODUCTION For an operational radar, backscatter of the transmitted signal by elements of the sea surface often places severe limits on the detectability of returns from ships, aircraft and missiles, navigation buoys, and other targets sharing the radar reso-lution cell.

These datasets are used for machine-learning research and have been cited in peer-reviewed academic journals. Datasets are an integral part of the field of machine learning. Major advances in this field can result from advances in learning algorithms (such as deep learning), computer hardware, and, less-intuitively, the availability of high-quality training datasets. According to the dictionary, clutter is "A collection of things lying about in an untidy mass." That's pretty general. It also means that while some clutter needs to be purged (thrown out, donated, sold), some just need to be cleaned up and put away.

The GTI model for sea clutter proposed in underestimates sea clutter reflectivity at sea states up to 3 compared to experimental data.

Secondly, take advantage of the classifier to realize the feature classification. Thus, we study the characteristics of sea clutter. Under complex sea conditions, ship detection from remote sensing images is easily affected by sea clutter, thin clouds, and islands, resulting in unreliable detection results.

In this paper, an end-to-end convolution neural network method is introduced that combines a deep convolution neural network with a fully connected conditional random field.

Finally, classification of radar returns other than from hydrometeors is described. Specifically, polarimetric methods to identify land and sea clutter, biological scatterers, chaff, smoke plumes, dust storms, and volcanic ash are presented. Chapter 6 Surface and Volume Clutter Clutter Definition Clutter is a term used to describe any object that may generate unwanted radar returns that may interfere with normal radar operations.

Parasitic returns that enter the radar through the antenna™s main lobe are called main lobe clut. Marcie Lovett, author of The Clutter Book, will motivate you to make the changes you want.

Learn to let go of what you don't need and find room for what you value. The direct, accessible writing style and interactive exercises will inspire you to succeed. In this book, Marcie guides you through the process of letting go of the clutter that is Reviews: 5.

Correlated spiky clutter consisting of persistent clumped returns. At any one time, an A-scope trace looks like a comb with semi-randomly spaced teeth. The whole pattern moves at speeds up to 40 knots. Individual spikes persisted for 10 to 40 s and the clutter level.

Clutter is a term used for unwanted echoes in electronic systems, particularly in reference to echoes are typically returned from ground, sea, rain, animals/insects, chaff and atmospheric turbulences, and can cause serious performance issues with radar systems. Year of No Clutter is a deeply inspiring--and frequently hilarious -- examination of why we keep stuff in the first place, and how to let it all go." - Chelle's Write.
