This paper addresses the results of the instrument and product performance verification, radiometric and geometric calibration achieved since the end of the respective Sentinel-1 A and B commissioning phases.
The on-going European Space Agency (ESA) Sentinel-1 mission has introduced an important change in the management of SAR data, freely opening the archives of the generated Level-0 and Level-1 products to the scientific community.
The paper introduces a couple of techniques for the enhanced processing of TOPSAR data. Both techniques are based on repeated passes of the sensor over the same area. The first technique combines two “de-synchronized” acquisitions, useless for interferometric purposes, to obtain an “enhanced resolution” image of the coherent scatterers in the scene. The second technique exploits the Permanent Scatterers...
The increasing interest in bistatic SAR missions and in the new opportunities they can create has led to the development during time of a new set of processing solutions, as wide as the possible configurations assumed by the involved satellites and the corresponding applications.
This paper addresses the results of the instrument and product performance verification, radiometric and geometric calibration achieved during the since commissioning and routine phase.
In this paper the Sentinel-1 on board Data Compression Estimation tool (COM) is presented. Sentinel-1 SAR antenna is known to produce a large volume of data during acquisition and the Flexible Dynamic Block Adaptive Quantization (FDBAQ) compression scheme has been built to efficiently overcome this problem. The COM processor is a software suite that emulates the FDBAQ on-board operations to provide...
