Bistatic TerraSAR-X/F-SAR Spaceborne-Airborne SAR Experiment: Description, Data Processing and Results [PDF]

, 2010
We report about the first X-band spaceborne-airborne bistatic SAR experiment, using the German satellite TerraSAR-X as transmitter and DLR's new airborne radar system F-SAR as receiver. The data were acquired early November 2007.

Al3+/Ta5+ Co‐Doping Promotes Homogeneous Li+ Transport Enabling High Performance Ni‐Rich Layered Oxide Cathodes

Advanced Functional Materials, EarlyView.
Al3+/Ta5+ co‐doping refines the primary particles of LiNiO2, reduces Li/Ni antisite disorder, and expands the c‐axis lattice parameter, thereby enabling faster and more homogeneous Li+ transport. Such rapid and homogeneous Li+ transport suppresses high‐voltage phase transitions and microcrack formation, ultimately improving the rate capability and long‐

Advanced Multi-Channel SAR Imaging - Measured Data Demonstration [PDF]

, 2009
Synthetic Aperture Radar (SAR) is a well-established technique for remote sensing of the Earth. However, conventional SAR systems relying on only a single transmit and receive aperture are not capable of imaging a wide swath with high spatial resolution.

Fractal dimension images from SAR images [PDF]

2014 IEEE International Conference on Image Processing (ICIP), 2014
In this paper we present the description of the image-processing issues underlying the estimation of the fractal dimension of natural surfaces from their corresponding synthetic aperture radar images. The choice of the spectral-estimation method is a key issue, due to the special nature of the problem at hand.

Engineering the Assembly Freedom of Donor–Acceptor Type Self‐Assembled Monolayers Toward Efficient and Stable Flexible Perovskite Photovoltaics

Advanced Materials, EarlyView.
Assembly freedom engineering breaks the vertical alignment constraint of donor–acceptor self‐assembled monolayers, tuning their assembly freedom to achieve quasi‐random molecular orientation. This strategy simultaneously boosts interfacial charge transport and mechanical robustness, enabling high‐efficiency and mechanically stable flexible perovskite ...

Extended Subaperture Imaging Method for Airborne Low Frequency Ultrawideband SAR Data

Sensors, 2019
The subaperture processing is one of the essential strategies for low frequency ultrawideband synthetic aperture radar (LF UWB SAR) imaging, especially for the real-time LF UWB SAR imaging because it can improve the parallelization of the imaging ...

Radargrammetric SAR Image Processing

, 2009
Throughout history, humans have tried to represent what they see through images. Mapmakers have always sought ways inwhich to represent both the location and the three dimensional shape of land. At the beginning, the way to obtain a 3D representation of land was to measure planimetry and height (as we can identify later by longitude, latitude and ...
