Definition of ICESat Selection Criteria for their Use as Height References for TanDEM-X [PDF]

, 2010
The TanDEM X satellite synthetic aperture radar (SAR) mission has the goal to deliver a high-precision global digital elevation model (DEM). The X band SAR interferometry (InSAR)-derived DEMs contain absolute and relative height errors that have to be ...

Three-dimensional Tomographic Imaging of Urban Buildings and Structures Using Chinese Commercial SAR Satellite Data

Leida xuebao
A single Synthetic Aperture Radar (SAR) image can capture only two-dimensional information, and traditional multitemporal Interferometric SAR (InSAR) techniques struggle with the layover problem, particularly in urban areas.

Bidirectional SAR Imaging Mode [PDF]

, 2013
The paper introduces the Bi-Directional (BiDi) SAR imaging mode, i.e. the simultaneous imaging of two directions by one antenna into one receiving channel, and presents short-term time series of images and interferograms acquired by the TerraSAR-X and ...

Activation of Metal Complexes With Ultrasound Waves for Targeted Anticancer Therapy

Angewandte Chemie International Edition, EarlyView.
Ultrasound enables non‐invasive activation of metal‐based therapeutics deep within tumors. Acoustic cavitation can drive sonodynamic reactive oxygen species generation or mechanochemical metal–ligand bond dissociation, enabling controlled release of bioactive payloads.
