چکیده

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 interferograms acquired over a site near the city of Be rlin.

Performance of Envisat/ Asar Interferometric Products

ENVISAT/ ASAR interferometry is a useful tool for the retrieval of geoand bio-physical parameters. In this paper the aim is show the quality of interferometric ENVISAT/ ASAR products. This objective will be approached in two ways. First, the timing accuracy of various ENVISAT/ ASAR products is evaluated. The geometric calibration and validation includes the determination of slant-range and azim...

ENVISAT Interferometry for mapping and monitoring: preliminary results

In the paper we provide an overview of a technique for getting repeat pass interferometric surveys by exploiting the very different ASAR modes: Image Mode, Alternating Polarization and Wide-Swath Mode. We briefly discuss the architecture of the modular processor, able to accept any of the cited modes, together with a DEM (if available, if not a global one like GTOPO30 or ENVI is assumed by defa...

The Asar Wide Swath Single Look Complex Product: Properties and Applications

In the ENVISAT products list, ESA is going to add a new one: the ASAR Wide Swath Complex product, containing Wide Swath Mode (WSM) phase preserved data focused on a coherent grid. The image will cover an area of 400 x 400 km, at a resolution of approximately 30 × 120 m (range, azimuth) with three independent looks, interleaved in azimuth. The intended applications are interferometry, wavewind s...

Calibration of Interferometric Envisat/asar Image Mode Products

Interferometric data processing requires careful calibration and validation of the complex input products. Interferometric calibration comprises geometric and phase accuracy aspects. With respect to geometry, orbit and timing parameter have to be calibrated in order to allow accurate geo-coding and optimal processing of the interferometric products. Phase accuracy of the input complex products ...

Sar 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...
