PARSAX An Informal Look at Radar Technology and Applications within TU Delft


…that does not mean it is fundamentally wrong

The Economist logoAn article "The clouds of unknowing" in The Economist summarizes the scientific and public discussions on global warming, where they try to explain to the readers that "There are lots of uncertainties in climate science. But that does not mean it is fundamentally wrong."

In any complex scientific picture of the world there will be gaps, misperceptions and mistakes. Whether your impression is dominated by the whole or the holes will depend on your attitude to the project at hand. You might say that some see a jigsaw where others see a house of cards. Jigsaw types have in mind an overall picture and are open to bits being taken out, moved around or abandoned should they not fit. Those who see houses of cards think that if any piece is removed, the whole lot falls down. When it comes to climate, academic scientists are jigsaw types, dissenters from their view house-of-cards-ists.

It was pleasure for me to find in this article arguments and explanations which we are already using during last decade trying to argue the importance of clouds in the climate system and the necessity to develop new remote sensing instruments and techniques for long term, continuous clouds observations and their parameters retrieval.

Remote Sensing Symposium in TU Delft

The second Remote Sensing Symposium (RSS) will be hosted by the Delft University of Technology, on May 19, 2010. Following a successful first symposium organized by VU Amsterdam in 2009, this symposium seeks to stimulate the exchange of ideas among a community of PhD students and researchers on various fields of Remote Sensing techniques and their applications. During the symposium, PhD candidates from all over the Netherlands will present their research on the field of Remote Sensing, either through an oral presentation, or through a poster. The Remote Sensing Symposium will be held at the Aula Conference Centre of Delft University of Technology.Second Remote Sensing Symposium in TU Delft

Special Detection Technique (Polarimetry) and Remote Sensing


Yesterday I've received a message from Vladimir Kyovtorov (Institute of Information Technologies, Bulgarian Academy of Sciences) with information about meeting "Special Detection Technique (Polarimetry) and Remote Sensing", which will take place 12 - 25 Sep 2010 in Kyiv, Ukraine. It is organized by NATO Advanced Study Institute. The chairs are Yaroslav Yatskiv (Main Astronomical Observatory, National Academy of Sciences of Ukraine, Kyiv, Ukraine) and Michael Mishchenko (NASA Goddard Institute for Space Studies, New York, USA).

The goal of the meeting is to present high level tutorial courses and more specialized lectures on the most recent advances in polarimetric detection, characterization, and remote sensing, including military and environmental monitoring as well as terrestrial, atmospheric, and astrophysical characterization. We will present, discuss, and teach techniques developed in various disciplines to acquire information from the polarization signal of scattered electromagnetic waves. We will identify techniques that have been especially successful for various applications as well as the future needs of the research communities. Most of all, it is expected that the inclusion of researchers from various disciplines will lead to cross-pollination of ideas and foster collaborations that will improve research efficiency.

Application deadline is 20 April 2010. More information about participation and event's program can be found on official web-page.


Bistatic Radar Polarimetry by Zbigniew H. Czyz

The Wexford College Press published in 2008 a book of Zbigniew H. Czyz (Poland) where he analyzed possible approaches for implementation of the radar polarimetry principles to bistatic radar.

Bistatic Radar Polarimetry by Zbigniew H. CzyzZbigniew H. Czyz "Bistatic Radar Polarimetry: Theory & Principles." Wexford College Press, 2008. - 256 pp.
ISBN-10: 1934939161; ISBN-13: 978-1934939161.


  1. Introduction
  2. Radar Polarimetry
  3. Polarization of Monochromatic Plane Waves
  4. Polarization Sphere of Tangential Phasors
  5. Rotation Transformation on the Sphere
  6. Change of Phase, Orthogonality and Spatial Reversal Transformation on the Sphere
  7. Scattering and Propagation Matrices
  8. The Poincare Sphere Analysis
  9. Poincare Sphere Geometrical Model of the Scattering Matrix
  10. Special Polarizations of the Bistatic Scattering Matrix
  11. Constant Received Power Curves on the Poincare Sphere
  12. The Basis-Invariant Decompositions of the Sinclair Matrix
  13. Decomposition of the Partially Depolarizing Kennaugh Matrix into Four Non-Depolarizing Components
  14. The Polarimetric Two-Ports
  15. The Four-Sphere of Partial Polarization and Its Applications
  16. Appendices.

Unfortunately, the TU Delft library does not have this book. But there is available on-line report "Fundamentals of Bistatic Radar Polarimetry Using the Poincare Sphere Transformations. A Comparison of the Matrix and Quaternionic Formulation of the Optical and Radar Polarimetry", written in 2002 by the same author 46 pages, which, probably, can give first impression about book contents and author's approach to the problem.

P.S. Even more full version of previously mentioned report is available on-line: "Fundamentals of Bistatic Radar Polarimetry Using the Poincare Sphere Transformations" (1 June 2001) - 247 pages.

I was looking for this cartoon long time. Thank you, Pascal, now I have a link to its author's site.
