Preliminary results from most recent SAR airborne campaigns by MetaSensing

MetaSensing B.V.(1) is a Dutch company producing and operating Synthetic Aperture Radar (SAR) sensors at high resolution and different frequency bands, including P-, L-, C-, X-and Ku. By operating its most recent SAR sensors in the framework of different projects MetaSensing showed how diverse SAR imagery techniques can be applied to different areas of remote sensing, offering an effective tool for monitoring and mapping purposes. The present paper gives an overview about the last achievements of MetaSensing during a recent airborne measurement mission within the AlpTomoExpcampaign, also showing some preliminary results. A fully-polarimetric L-band radar system has been successfully operated in March 2014 within the framework of the future SAOCOM+ mission currently under investigation by the European Space Agency (ESA). At these low frequencies penetration capabilities for several meters is possible on dry snow. More than 40 fully polarimetric images have been focused by MetaSensing of a glacier of the Otzal Alps, in Austria, within the framework of the AlpTomoExp campaign. Thanks to the good interferometric coherence of the acquired images, further tomographic processing has been possible for 3D images generation showing the vertical profile of the monitored scenario.
