Channel Phase Error Compensation for MIMO‐SAR
International Journal of Antennas and Propagation, Volume 2014, Issue 1, 2014., 2014 Multi‐input multioutput (MIMO) is a novel technique to achieve high‐resolution as well as wide swath in synthetic aperture radar (SAR) systems. Channel imbalance is inevitable in multichannel systems that it declines the imaging quality. Generally, the imbalance cannot be fully compensated by simple internal calibration in a MIMO‐SAR system.

Signal Processing for Digital Beamforming FMCW SAR
Mathematical Problems in Engineering, Volume 2014, Issue 1, 2014., 2014 According to the limitations of single channel Frequency Modulation Continuous Wave (FMCW) Synthetic Aperture Radar (SAR), Digital Beamforming (DBF) technology is introduced to improve system performance. Combined with multiple receive apertures, DBF FMCW SAR can obtain high resolution in low pulse repetition frequency, which can increase the ...

Treating the innocent victims of trolleys and war
Bioethics, Volume 39, Issue 1, Page 18-25, January 2025.Abstract Both trolleys and war leave innocent victims to suffer death and injury. Trolley problems accounting for the injured, and not only the dead, tease out intuitions about liability that enhance our understanding of the obligation to provide compensation and medical care to civilian victims of war.
