Ultra Wide Swath Imaging With Multi-Channel SAR Systems [PDF]

, 2008
Multi-channel radar systems allow for overcoming the inherent limitation of conventional synthetic aperture radar (SAR). An example is the combination of digital beamforming on receive in elevation with multi-aperture SAR signal reconstruction in azimuth

Reconciling the predictions of microlensing analysis with radial velocity measurements for OGLE-2011-BLG-0417

, 2018
Microlensing is able to reveal multiple body systems located several kilo-parsec away from the Earth. Since it does not require the measurement of light from the lens, microlensing is sensitive to a range of objects, from free-floating planets to stellar

Possible microlensing event in the direction of M31

, 2003
The Cousin R and I band photometric observations of ~ 13' × 13' field in the direction of M31 galaxy have been carried out during 1999-2001 to search for microlensing events using pixel technique.
