Pasquali, P; Monti Guarnieri, A; D'Aria, D; Costa, L; Small, David; Jehle, Michael; Rosich, Betlem (2007). ALOS PALSAR verification processor. In: Envisat Symposium 2007, Montreux (CH), 23 April 2007 - 27 April 2007, online.

Abstract

This paper presents a verification processor, developed under ESA contract, for the generation of polarimetric, interferometric and polarimetric-interferometric geocoded products derived from SAR data obtained from the ALOS PALSAR instrument.
The processor, developed with a modular approach, contains the following main elements:
- Phase-preserving fine resolution processor; - Phase-preserving ScanSAR processor;
- Interference removal tools;
- Polarimetric calibration tools;
- Polarimetric analysis tools;
- Fine resolution interferometric processor; - ScanSAR interferometric processor;
- Polarimetric-interferometric processor;
- Geocoding;
- Atmospheric modelling tools.
All of the PALSAR acquisition modes (i.e. stripmap in one, two and full polarisations as well as ScanSAR) are supported both starting from raw and focused data.
The processor architecture is presented; highlights are given on modules and algorithms specifically developed for handling the peculiarities of these L-Band SAR data. Examples are shown obtained during the first year of operation of the system, over a number of test sites and of different types of products and acquisition modes.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
