چکیده

An add-on tool to be applied to COSMO-Skymed high resolution SAR images to improve maritime surveillance capabilities is here described. The proposed processing performs maritime targets detection, targets extraction and refocusing in an automatic, semi-automatic and manual manner. A deep knowledge of radar processing is not needed since an intuitive Graphic User Interface (GUI) guides the user through the whole processing chain. The high level processing chain and its integration in the GUI are described in this paper. Results on CSK dataset are given.

SAR interferometry analyses and experiments with COSMO-SkyMed

The new X-band SAR missions provide SAR images characterized by a much higher resolution, opening new possibilities for SAR interferometry. Thanks to the high resolution it is expected to find a larger number of coherent points or persistent scatterers per unit area, resulting in more detailed and accurate measurements by means of SAR differential interferometry techniques. Among the other char...

Post-seismic infrastructure damage assessment using high-resolution SAR satellite data

The Wenchuan Earthquake on May 12, 2008, devastated a vast area in Sichuan, China. The swift rescue and disaster management measures of the Chinese government have been supported by radar remote sensing from the very beginning. The new high-resolution synthetic aperture radar (SAR) satellites, like COSMO-SkyMed and TerraSAR-X, have been used for damage assessment and rapid mapping. Unfortunatel...

A Study for Cosmo-skymed Sar Multi-beam of Second Generation (msar-2g)

This paper discusses the potentialities obtained by splitting the antenna of the COSMO-SkyMed SAR developed by Alenia Spazio under contract of Italian Space Agency and Italian Ministry of Defence into multiple sub-apertures. The modified sensor is shown to allow: (a) clutter cancellation and detection of slowly moving ground targets for surveillance purpose, (b) sea current/wave monitoring by a...

Shoreline detection: capability of COSMO-SkyMed and high-resolution multispectral images

This study aims to extract the instantaneous shoreline from remote sensing data acquired with very high resolution multispectral and SAR sensors. The capabilities of IKONOS, GeoEye and COSMO-SkyMed for shoreline detection are tested in the Venice littoral (Italy) by classifying the imagery into its land/water components. GPS measurements synchronously to the COSMO-SkyMed acquisitions are carrie...

Extension of Wavenumber Domain Focusing for spotlight COSMO-SkyMed SAR Data

In this work we describe a method to handle curved orbits in wavenumber domain focusing algorithm for high-resolution SAR data acquired by Low Earth Orbit satellites using spotlight mode. The standard wavenumber domain focusing algorithm make assumptions that start to be invalid when applied to high-resolution spotlight SAR data acquired in spaceborne low Earth orbit (LEO) configurations. The a...
