First results of the ALOS PALSAR verification processor


Pasquali, P; Monti Guarnieri, A; D'Aria, D; Costa, L; Small, David; Jehle, Michael; Rosich, Betlem (2007). First results of the ALOS PALSAR verification processor. In: ESA PolInSAR 2007 Workshop, Frascati (I), 22 January 2007 - 26 January 2007, online.

Abstract

Among the several applications that will take advantage of the newly available data from the ALOS PALSAR instrument, considerable interest is in the peculiar features that derive from the penetration and polarimetric capabilities of the system.
These capabilities, new for a single spaceborne sensor, need specific software tools for the processing of the different acquisition modes. This paper presents a verification processor, developed under ESA contract, for the generation of polarimetric, interferometric and polarimetric-interferometric geocoded products derived from ALOS PALSAR data.
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.
The processor architecture is presented; highlights are given on specific modules and algorithms. Early results are shown, in particular of the processing of polarimetric and polarimetric-interferometric data over different test sites.
