Airborne Synthetic Aperture Radar: Models, Focusing and Experiments

open access: yes, 2006
Synthetic Aperture Radar (SAR) is a remote sensing technique that allows the generation of microwave images of the Earth surface, independently of weather condition and of sun illumination.

In Situ Contact Angle Measurement for Autonomous Spin Coating in Self‐Driving Labs

open access: yesAdvanced Intelligent Discovery, EarlyView.
A vision‐based add‐on transforms commercial spin coaters into autonomous modules of Self‐Driving Labs. Combining a width‐scaled U‐Net with classical geometric analysis, the system simultaneously measures contact angles and estimates substrate pose using a single camera.

Airborne lidar observations supporting the ADM-Aeolus mission for global wind profiling

open access: yes, 2012
The Atmospheric Dynamics Mission ADM-Aeolus of ESA will be the first lidar mission to sense the global wind field from space. The instrument is based on a direct-detection Doppler lidar operating at 354.9 nm with two spectrometers for aerosol/cloud ...

Estimation of tree lists from airborne laser scanning by combining single-tree and area-based methods [PDF]

open access: yes, 2010
Individual tree crown segmentation from airborne laser scanning (ALS) data often fails to detect all trees depending on the forest structure. This paper presents a new method to produce tree lists consistent with unbiased estimates at area level.

Versatile Standing Wave Generation Between Arbitrarily Oriented Surfaces Using Acoustic Metasurface Deflectors and Retroreflectors

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
A novel method for generating versatile standing wave fields using an acoustic metasurface deflector and retroreflector is introduced. By overcoming traditional constraints of parallel surfaces, the approach enables customizable wave patterns and enhances applications in particle manipulation.

First Evaluations of Airborne InSAR Time-Series

open access: yes, 2006
To allow time-series analysis of airborne SAR images using PSs (Permanent Scatterers), this paper has two main objectives. The first is to show, in a quantitative way, that there is a compromise between the number of images used to detect PSs, their ...

Recent Developments and Applications of Multi-Pass Airborne Interferometric SAR using the E-SAR System [PDF]

open access: yes, 2008
Airborne SAR systems are traditionally considered to be a suitable testbed for the demonstration of new Earth observation data acquisition techniques and for the development of new applications based on the acquired multi parameter data sets ...

Soft Active Electromyography Interface for Machine Learning‐Enabled Silent Speech Recognition

open access: yesAdvanced Intelligent Systems, EarlyView.
A soft, hand‐worn electromyography interface enables intent‐driven silent speech recognition without continuous facial attachment. The device integrates liquid‐metal interconnects, a transparent flexible circuit, and elastomer encapsulation with a fingertip electrode that contacts perioral muscles only on demand.

An Investigation on Atmospheric Effects in Airborne Interferometric SAR data

open access: yes, 2007
The results of an experiment on atmospheric effects in interferometric SAR data are presented. The main purpose of the experiment was to investigate on the influence of the troposphere on airborne synthetic aperture radar measurements, acquired by DLR’s ...
