Measurement of Ionospheric TEC in Spaceborne SAR Data [PDF]
IEEE Transactions on Geoscience and Remote Sensing, 2010 The propagation of spaceborne radar signals operating at L-band frequency or below can be seriously affected by the ionosphere. At high states of solar activity, Faraday rotation (FR) and signal path delays disturb radar polarimetry and reduce resolution in range and azimuth.

A golden age for spaceborne SAR systems [PDF]
2014 20th International Conference on Microwaves, Radar and Wireless Communications (MIKON), 2014 Spaceborne Synthetic Aperture Radar (SAR) is the only imaging sensor technology that can provide all-weather, day-and-night and high-resolution images on a global scale. Today, SAR data are used for a multitude of applications ranging from geoscience and climate change research, environmental monitoring, 2-D and 3-D mapping, change detection, 4-D ...

Efficient Time-Domain Image Formation with Precise Topography Accommodation for General Bistatic SAR Configurations [PDF]
, 2011 Due to the lack of an appropriate symmetry in the acquisition geometry, generalised bistatic SAR cannot benefit from the two main properties of low-to-moderate resolution monostatic SAR: azimuth-invariance and topography-insensitivity.
