ASAR ScanSAR modes: quality enhancement
This paper focuses on the optimization of the image quality for the ENVISAT ASAR ScanSAR modes. The best tradeoff between Noise Equivalent 0 (NE 0) and Equivalent Number of Looks (ENL) is achieved by optimizing both system and processing parameters within the instrument constraints. An end-to-end model to validate the study has been used. Thereafter a novel phase preserving focusing technique i...
متن کاملGeometric Calibration and Validation of ASAR Imagery
We describe work conducted to calibrate and then validate the geometry of ENVISAT ASAR products. A systematic error in range location was observed in ASAR products during the commissioning phase. A careful and complete analysis has been performed to establish the precise error. It has been compensated by updating the range gate bias (or sampling window start time bias). Validation of the absolu...
متن کاملMonitoring Agricultural Activities Using Asar Envisat Data
Space borne radar data facilitates continuous monitoring of almost any location on the earth (limitations in polar zones) with quite low costs. Almost weather-independent operation of radar systems enables a reliable and continuous record of data from earth’s surface. In the framework of an ESA pilot project (AO335), ENVISAT polarimetric SAR data of years 2004 and 2005 are examined for their us...
متن کاملAsar Imp Image Quality (vv Polarisation)
This paper gives details of image quality analysis of ASAR image mode IMP VV polarisation products performed during the ASAR commissioning phase. Initially, a description of the analysis methodology and performance assessment tools, image properties and example IMP products is given followed by the image quality analysis. This analysis includes format verification, impulse response function mea...
متن کاملAsar Wave Mode First Geophysical Results
Some geophysical calibration results on the level 1 ASAR WVI products are presented in the continuity of the investigations performed on the ERS1/2 SAR Wave Mode products. Investigations have been focussed on comparisons with co-located ECMWF winds. In particular, a calibration constant is tentatively derived using CMOD-IFREMER model function. Following standard azimuthal resolution losses over...
