StaMPS Permanent Scatterer. Processing SAR data of rugged terrain by time-domain back-projection Othmar Frey and Erich H. Meier and Daniel R. Nuesc¨ h Remote Sensing Laboratories, University of Zurich, CH-8057 Zurich, Switzerland ABSTRACT Processing of SAR images of rugged terrain deserves special care because the topography affects the focused image in a number of ways. StaMPS Permanent Scatterer processing¶. : +49 8153 28-1369 It is the only 24/7 remote sensing imaging system. The processing steps involved to produce Level-1 data products include pre-processing, Doppler centroid estimation, single look complex focusing, and image and post-processing for generation of the SLC and GRD products as well as mode specific processing for assembling of multiple sub-swath products. Unlike with conventional imaging tools, SAR systems require data processing to form the final image.

StaMPS (Stanford Method for Persistent Scatterers) is a software package that implements an InSAR persistent scatterer (PS) method developed to work even in terrains devoid of man-made structures and/or … SAR Doppler processing Another alternative method to perform SAR processing is to incorporate Doppler processing. SAR processing SAR-EDU>Data processing>SAR Specific Data Formats>January 2012 Radiometric adjustment Further radiometric corrections, compensating for effects of local pixel scattering area and local incidence angle on the local backscatter, can be carried out. With a single interferometric pair (two SAR images) and non-zero baseline: the interferometric phase contains both altitude and motion contributions (see Equation 1.1).

In practice, this process is performed in several 1-D steps, A cheat sheet outling the workflow for pre-processing L1 Synthetic Aperture Radar data. The SLC processing takes as input, the signal data and the pre-processing output including orbit information and Doppler centroid estimation polynomials. The signal processing achieves the same cancellation of signals coming from azimuths outside out desired 1 meter ground strip as an actual 300 meter antenna would do. 3.

Level-1 SLC Processing Algorithms Single Look Complex (SLC) processing focuses the data in azimuth and range to form an image. The following processing steps are required: 1) An available DEM must be re-sampled from geographic to SAR coordinates and the elevation must be converted into SAR uses the motion of the radar antenna over a target region to provide finer spatial resolution than conventional beam-scanning radars. German Aerospace Center (DLR) Remote Sensing Technology Institute, SAR Signal Processing Oberpfaffenhofen 82234 Weßling Tel. This processing technique is known as line-by-line processing. Synthetic-aperture radar (SAR) is a form of radar that is used to create two-dimensional images or three-dimensional reconstructions of objects, such as landscapes. In its most abstract form, this is the process of performing a frequency domain correlation of the received signal with a 2-D system transfer function.
It has cloud penetrating capabilities because it uses microwaves; it has day and night operational capabilities because it is an active system; and its ‘interferometric configuration’, Interferometric SAR or InSAR, allows accurate measurements of the radiation travel path because it is coherent.

Starting from optical techniques, over analog electronics up to modern digital SAR processors, several possibilities are existing to realize the necessary computational steps. Nowadays, in the time of very powerful digital hardware, mostly digital methods are used, either realized in software or by using hardware signal-processing. Synthetic aperture radar (SAR) is a powerful tool capable of producing high-resolution imagery day or night and in all weather conditions. SAR PROCESSING SAR processing is the transformation of raw SAR signal data into a spatial image. Sea ice signatures are detectable by Synthetic Aperture Radar (SAR) Satellites like RADARSAT-1, ERS1, ERS2, ENVISAT, JERS, and the newest generation of SAR systems like RADARSAT-2 and Terra SAR-X.
Part of the emitted radar energy (5.6 cm wavelength) directed at the ocean is reflected back to the satellite because of the roughness of the sea surface and is imaged as a gray speckle [2].
