The relationship between radar backscatter cross section and ocean wave parameters at low incidence angles

Xiaoqing Chu; Yijun He; Gengxin Chen 2009 IEEE International Geoscience and Remote Sensing Symposium, 2009

Using collocated data set of Tropical Rainfall Mapping Mission (TRMM) precipitation radar (PR) and buoy wind and wave measurements, we study the relationship between the Ku-band radar backscatter cross section (¿°), radar incidence angle (¿), the buoy measured near surface wind speed in 10m (U10), significant wave height (SWH), wave steepness (¿), and wave age (ß).

Sonar image segmentation using the angular dependence of backscattering distributions

G. Le. Chenadec; J. M. Boucher Europe Oceans 2005, 2005

In high resolution sonar imaging, the K-distribution has shown interesting properties for describing the statistics of backscattered intensity. This distribution is a function of two parameters. The first one is the mean intensity which is classically angular dependent. It has been found that the second one, the shape parameter, is also angular dependent. The K-distribution shape parameter shows two types ...

  • Characterization Techniques for Film Characteristics

    This chapter shows data regarding whisker phenomena that are characterized by the most recent transmission electron microscopy (TEM), scanning electron microscopy (SEM), and electron backscatter diffraction (EBSD) techniques. It introduces several examples of SEM image use in tin whisker analysis: observation of tin whisker shape, measurement of tin whisker length and kink angle, and confirmation that tin whiskers do indeed generate from the base metal. The chapter describes concrete examples of whisker analysis that use the techniques. The chapter also discusses general crystal orientation characterization techniques and then focuses on the principles of and advances in EBSD and its use in investigating the effects of crystal orientation on tin whisker formation. Many examples of characterization by using TEM, SEM, and EBSD techniques for tin and tin???based alloy finishes show how to clarify the essential characteristics of the films so that the authors can deepen their understanding of whisker formation mechanisms.

  • Index

    **Discusses the growth mechanisms of tin whiskers and the effective mitigation strategies necessary to reduce whisker growth risks** This book covers key tin whisker topics, ranging from fundamental science to practical mitigation strategies. The text begins with a review of the characteristic properties of local microstructures around whisker and hillock grains to identify why these particular grains and locations become predisposed to forming whiskers and hillocks. The book discusses the basic properties of tin-based alloy finishes and the effects of various alloying elements on whisker formation, with a focus on potential mechanisms for whisker suppression or enhancement for each element. Tin whisker risk mitigation strategies for each tier of the supply chain for high reliability electronic systems are also described. * Discusses whisker formation factors including surface grain geometry, crystallographic orientation-dependent surface grain boundary structu e, and the localization of elastic strain/strain energy density distribution * Examines how whiskers and hillocks evolve in time through real-time studies of whisker growth with the scanning electron microscope/focused ion beaming milling (SEM/FIB) * Covers characterization methods of tin and tin-based alloy finishes such as transmission electron microscopy (TEM), scanning electron microscopy (SEM), and electron backscatter diffraction (EBSD) * Reviews theories of mechanically-induced tin whiskers with case studies using pure tin and other lead-free finishes shown to evaluate the pressure-induced tin whiskers _Mitigating Tin Whisker Risks: Theory and Practice _is intended for the broader electronic packaging and manufacturing community including: manufacturing engineers, packaging development engineers, as well as engineers and researchers in high reliability industries.
