The Sentinel-1 SARs are designed to achieve global coverage with short repeat intervals. Using a constellation of two satellites and operating these in a special ScanSAR mode permits providing excellent multi-temporal data. Therefore, multi-temporal processing techniques are becoming very relevant. In our processing and retrieval concept we are using a two stage approach. The first stage deals...

Modern SAR sensors are increasingly offering wide swaths, enabling shorter revisit intervals than were hitherto possible. The new open data policy of Sentinel-1 enables the development of higher level products, built on a foundation of level 1 SAR imagery that meets a high standard of geometric and radiometric calibration. We systematically process slant or ground range Sentinel-1 data to...

Synthetic Aperture Radar (SAR) interferometry and Coherent Change Detection (CCD), both monostatic and bistatic, depend on high coherence between repeat pass SAR images pairs. In principle these approaches allow a sensitive change detection for example due to ground subsidence or due to vehicle tracks, both applications having clear civilian and military benefits.
However there is usually a...

Ka-band RADAR frequency range has not yet been used for Synthetic Aperture Radar (SAR) from space so far, but this technology may lead to important applications for the next generation of SAR space sensors. First of all the small wavelength makes small baseline suitable for interferometric applications, thus enabling a relatively simple implementation of single pass interferometry from a...

High resolution (<1m, single look images), X-band airborne synthetic aperture radar (SAR) imagery was collected for sites of environmental interest in Scotland. The SAR system utilised was Selex ES’s novel, compact, low-cost airborne experimental platform. Its size, power consumption and lightweight build allow it to be placed on helicopters, fixed wing aircrafts and UAVs; making techniques...

Floodplain vegetation classification is an important issue in the Netherlands since the country is highly vulnerable to flooding. The resistance force exerted by vegetation on water flowing over or through it alters the water flow velocity, thus, it is important to classify and monitor the vegetation in such sensitive areas. Currently, this is done by means of aerial photography...
