This book was released on 2013-11-09 with total page 1076 pages. Available in PDF, EPUB and Kindle. Book excerpt: This foreword deals exclusively with the planning, organization, and execution of the Workshop's scientific as well as cultural programs. It is opened with a synopsis on how the global political changes that occurred immediately after the Workshop caused the ~elay in producing the proceedings, followed by a brief exposition on need, timeliness, and importance of this second ARW in the field of electromagnetic imaging, radar remote sensing, and target versus clutter di~rimination; and an outline of the objectives. An informal discussion about some of the organizational details, a retrospective summary of events, and a preview of the third workshop, planned for 1993 September 19-25, is intended to recapture the spirit of this second NATO Advanced Research Workshop (1988 September 18-24), and will reveal how successful it was in compar ison to the first of 1983 September 18-24, how its accomplishments may be appreciated and why a third and last workshop was requested by its participants to take place during 1993 September 19-25.
Download or read book Synthetic Aperture Radar Polarimetry written by Jakob J. van Zyl and published by John Wiley & Sons. This book was released on 2011-10-14 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the application of polarimetric synthetic aperture radar to earth remote sensing based on research at the NASA Jet Propulsion Laboratory (JPL). This book synthesizes all current research to provide practical information for both the newcomer and the expert in radar polarimetry. The text offers a concise description of the mathematical fundamentals illustrated with many examples using SAR data, with a main focus on remote sensing of the earth. The book begins with basics of synthetic aperture radar to provide the basis for understanding how polarimetric SAR images are formed and gives an introduction to the fundamentals of radar polarimetry. It goes on to discuss more advanced polarimetric concepts that allow one to infer more information about the terrain being imaged. In order to analyze data quantitatively, the signals must be calibrated carefully, which the book addresses in a chapter summarizing the basic calibration algorithms. The book concludes with examples of applying polarimetric analysis to scattering from rough surfaces, to infer soil moisture from radar signals.

Available in PDF, EPUB and Kindle. Book excerpt: A calibration scheme is described for a coherent scattering matrix radar to correct for non-ideal antenna polarisation characteristics and amplitude and phase inbalance between the receiver and transmitter channels. Calibration is achieved by measuring the receiver voltages corresponding to scattering the transmitted states from trihedral and dihedral reflectors. Neither the absolute nor relative phase of the calibration targets need to be known. (Great Britain).

Download or read book Polarimetric Techniques and Measurements at 95 and 225 GHz written by James Mead and published by . This book was released on 1991 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: The University of Massachusetts has developed two high-power portable polarimetric radars operating at 95 and 225 GHz. The 95 GHz coherent polarimeter is configured to measure the complex scattering matrix of a target by transmitting a pair of orthogonally polarized pulses in rapid succession. We have also developed a noncoherent 225 GHz polarimetric radar which directly characterizes the target Mueller matrix by transmitting a sequence of four or six polarization states. In addition to reviewing the radar design and calibration, this paper summarizes measurements of natural and man-made objects made to date. These measurements include several varieties of trees, terrain, and snowcover. A model which approximates the Mueller matrix with a single parameter is introduced for a restricted class of clutter and is found to accurately predict the polarimetric behavior of vegetation and terrain at low incidence angles. We also present a two parameter approximation of the Mueller matrix that accurately models scattering from snowcover at large incidence angles.

Available in PDF, EPUB and Kindle. Book excerpt: Recent advances in signal processing and remote sensing have highlighted the importance of bistatic radar systems for the purposes of environmental monitoring, surveillance, and tracking radar. The calibration of such systems has been problematic-much more so than similar monostatic systems, primarily as a result of the lack of reference objects suitable for calibrating at any given bistatic angle. This research deals with the problems of calibrating full-polarimetric laboratory-environment bistatic radar systems, including the lack of suitable calibration targets and procedures, and operational considerations such as alignment and mounting. Several popular bistatic calibration techniques are classified, evaluated, and comparisons are made between the relative merits of various calibration objects. The analysis addresses sensitivity to target alignment error, sensitivity to polarization impurity, and ease of implementation. Both theoretical concepts and practical considerations are discussed, based on measurements accomplished at the European Microwave Signature Laboratory (EMSL) of the Joint Research Center (JRC) in Ispra, Italy. Significant gains in co-polarized channel accuracy and cross- polarization purity are realized with calibrations that utilize the complete system distortion model and these conclusions are discussed in detail.
Download or read book Polarimetric Radar Imaging written by Jong-Sen Lee and published by CRC Press. This book was released on 2017-12-19 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recent launches of three fully polarimetric synthetic aperture radar (PolSAR) satellites have shown that polarimetric radar imaging can provide abundant data on the Earth’s environment, such as biomass and forest height estimation, snow cover mapping, glacier monitoring, and damage assessment. Written by two of the most recognized leaders in this field, Polarimetric Radar Imaging: From Basics to Applications presents polarimetric radar imaging and processing techniques and shows how to develop remote sensing applications using PolSAR imaging radar. The book provides a substantial and balanced introduction to the basic theory and advanced concepts of polarimetric scattering mechanisms, speckle statistics and speckle filtering, polarimetric information analysis and extraction techniques, and applications typical to radar polarimetric remote sensing. It explains the importance of wave polarization theory and the speckle phenomenon in the information retrieval problem of microwave imaging and inverse scattering. The authors demonstrate how to devise intelligent information extraction algorithms for remote sensing applications. They also describe more advanced polarimetric analysis techniques for polarimetric target decompositions, polarization orientation effects, polarimetric scattering modeling, speckle filtering, terrain and forest classification, manmade target analysis, and PolSAR interferometry. With sample PolSAR data sets and software available for download, this self-contained, hands-on book encourages you to analyze space-borne and airborne PolSAR and polarimetric interferometric SAR (Pol-InSAR) data and then develop applications using this data.

This book was released on 1986 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: A theoretical study has been made of calibration methods for both coherent and non-coherent polarimetric radars. Coherent systems are described in terms of measurement of the scattering matrix and non-coherent in terms of the Mueller Matrix. The similarity with the calibration of vector reflectometers is emphasized and exploited. Calibration is achieved by measuring the receiver voltages corresponding to scattering of the transmitted states by an odd bounce reflector and appropriately orientated thin wire gratings.
