Widefield Parametric Polar Format Algorithm for Spotlight SAR Imaging

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
For widefield synthetic aperture radar (SAR) imaging, range-dependent motion errors and range curvature are the main obstacle for range cell migration correction (RCMC) and azimuth focusing.

Design of LDO circuit based on curvature compensation reference closed-loop stability

open access: yesAIP Advances, 2023
In this paper, a low dropout (LDO) circuit based on a curvature compensation benchmark and closed-loop stability is designed. This circuit compensates for the higher order term of VBE in a BJT through the subthreshold characteristic of MOSFET and ...

A Curvature‐compensated Corrector for Drift‐Scan Observations [PDF]

open access: yesPublications of the Astronomical Society of the Pacific, 1998
Images obtained by drift-scanning with a stationary telescope are affected by the declination-dependent curvature of star trails. The image displacement to curvature and drift rate variation increases with the angular field of view and can lead to significant loss of resolution with modern large-format CCD arrays.
