Numerical Study of the Spatiotemporally-Varying Background Ionospheric Effects on P-Band Satellite SAR Imaging

open access: yesIEEE Access, 2020
At the relatively low frequency of the P-band spaceborne SAR, the background ionosphere is no longer treated as time-invariant, together with the spatial variation in the background ionosphere, and complicates the spaceborne SAR imaging.

Three-dimensional Imaging Algorithm for Multi-azimuth-angle Multi-baseline Spaceborne Synthetic Aperture Radar

open access: yesLeida xuebao, 2018
Traditional spaceborne Synthetic Aperture Radar (SAR) can acquire three-dimensional (3D) images by using multi-baseline SAR data, which solves the problem of layover in two-dimensional (2D) SAR image, however, there is still a problem of insufficient ...

Measurement of Ionospheric TEC in Spaceborne SAR Data [PDF]

open access: yesIEEE 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.
