ENVISAT ASAR data reduction: impact on SAR interferometry
An onboard synthetic aperture radar (SAR) signaldata reduction algorithm called Flexible Block Adaptive Quantization (FBAQ) was developed in 1994 for the Advanced SAR (ASAR) on the ENVISAT satellite. This paper presents work done in a follow-on study that examined the impact of the datareduction algorithm on the accuracy of two digital elevation models (DEM) produced by using the technique of r...
متن کاملFirst Analysis of Envisat/asar Image Mode Products for Interferometry
This paper summarizes the first results on interferometric ENVISAT/ ASAR image mode products [1]. We analyzed timing and geometric accuracy as well as the phase of a first interferogram from an IS2 image mode data set (VV polarized). According to the schedule the image mode products of this beam products are the first to be validated [2]. This interferogram is one of the first ENVISAT/ ASAR int...
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 کاملSar Processing Algorithms for Envisat Asar Image Mode and Alternating Polarization Mode in the Kspt Envisat Asar Processor
ABSTRACT: This paper describes the Extended Exact Transfer Function (EETF) algorithm used in the Kongsberg Spacetec (KSPT) ENVISAT ASAR processor, in addition to RADARSAT and ERS SAR processors from KSPT. This processor is required to handle and process data from image mode (IM), alternating polarization (AP) mode and wide swath (WS) mode. IM and AP mode are both processed using the EETF algori...
متن کاملApplication of Persistent Scatterer Interferometry for Land Subsidence Monitoring in Sydney, Australia using ENVISAT ASAR Data
The aim of this research is to investigate the terrain deformation in the metropolitan area of Sydney using multiple satellite radar imagery. The persistent scatterer interferometry (PSI) strategy developed at Geodesy and Earth Observing Systems Group (GEOS) of the University of New South Wales (UNSW) is used to map the land deformation in Sydney with C-band ENVISAT radar images in this study. ...
