Foreword
Remote sensing with polarimetric radar evolved from radar target detection along a
thorny historical path over the past sixty years as was assessed in greatest detail
during the two pioneering NATO ARWs*,y held in 1983 and 1988 during which more
than 120 leading experts from Western Europe, North America, Japan and Northeast
Asia were assembled to assess mathematical and physical methods of vector electromagnetic
scattering and imaging, dealing with purely mathematical modeling; and
where applied principles were tested against the first results on digital SAR imagery by
employing the NASA-JPL AIRSAR polarimetric images.
Since then, pertinent mission-oriented textbooks have been scarce and the quest
for developing a set of pertinent new research textbooks evolved. Instead, since
about 1992 an ever increasing number of radar and SAR polarimetricists gathered
at the annual IEEE-GRSS IGARSS symposia during which the Polarimetry Sessions
were arranged as strings of consequential events creating quasi Mini-Polarimetry
Workshops. We were all very involved in developing algorithms and tools for
advancing polarimetric SAR imaging, polarimetric interferometric imaging and
polarimetric multimodal SAR tomography and holography utilizing the superb
polarimetric imagery collected with the SIS-C=X-SAR shuttle missions of 1994,
and from the increasing number of airborne fully polarimetric SAR sensors (AIRSAR
of NASA-JPL, Convair C-580 of CCRS, E-SAR of DLR, RAMSES of
ONERA, PiSAR of CRL (NICT)=NASDA (JAXA)).
No new textbooks were forthcoming because the focus was directed toward
proofing the unforeseen capabilities of remote sensing applications using polarimetric
imaging radar modalities first, and instead several mission-oriented programs such as
the EU-TMR and EU-RTN collaboration on Radar Polarimetry, ONR-NICOP workshops
on wideband interferometric sensing & surveillance sprung up, being more
recently strengthened by the bi-annual EUSAR and the ESA-POLINSAR conferences,
all of which the two authors of this valuable book polarimetric radar imaging
contributed profoundly to advancing fundamental algorithm development as well as
its diverse applications.……………………………………………………
