The start-stop approximation is a standard tool for processing radar data in synthetic aperture imaging. It assumes that the antenna is motionless when a pulse is emitted and the scattered signal received, after which the antenna moves to its next sending/receiving position along the flight track. However, when the antenna is mounted on a satellite, as opposed to an airplane, its relatively high speed raises at least two questions. The first one is whether the image may be affected by the…

The start-stop approximation
For the analysis of the SAR data inversion algorithm, the start-stop approximation is employed, which is considered standard in the literature and assumes that the radar antenna is at standstill while it sends the interrogating pulse toward the target and receives the scattered response.
Dual Carrier Probing for Spaceborne SAR Imaging
This work concludes that the deterioration of SAR images was due to the mismatch between certain parameters of the actual received signal, which is slowed down by the temporal dispersion in the ionosphere, and the corresponding parameter of the matched filter, which was taken as if the propagation were unobstructed.
Resolution Analysis of Passive Synthetic Aperture Imaging of Fast Moving Objects
This paper introduces and analyzes a passive synthetic aperture radar system motivated by space surveillance radar networks for detecting, tracking, imaging, and identifying small debris in low-earth orbit and shows that its resolution is described by the ideal Rayleigh resolution formulas.
Theory of Waveform-Diverse Moving-Target Spotlight Synthetic-Aperture Radar
A theory for waveform-diverse moving-target synthetic-aperture radar in the case in which a single moving antenna is used both on transmission and on reception is developed and a formula for phase-space (position and velocity) imaging is developed.
Microlocal analysis of Doppler synthetic aperture radar
We study the existence and suppression of artifacts for a Doppler-based Synthetic Aperture Radar (DSAR) system. The idealized air- or space-borne system transmits a continuous wave at a fixed
Reduction of ionospheric distortions for spaceborne synthetic aperture radar with the help of image registration
We propose a robust technique for reducing the ionospheric distortions in spaceborne synthetic aperture radar (SAR) images. It is based on probing the terrain on two distinct carrier frequencies.
A Mathematical Model for SAR Imaging beyond the First Born Approximation
The foundations of the SAR ambiguity theory are revisited in order to address this and other existing inconsistencies, such as the absence of the Bragg scale in scattering, and a new model for radar targets that allows to compute the scattered field from first principles.
On SAR Imaging through the Earth's Ionosphere
The ionospheric phenomena, both deterministic and random, are shown to affect the azimuthal resolution of a SAR sensor stronger than the range resolution; also, the effect of randomness appears weaker than that of the baseline dispersion.

S ynthetic Aperture Radar (SAR) imagery has been used extensively within UK Defence and Intelligence for many years. Despite this, the exploitation of SAR imagery is still challenging to the
A Modified Cartesian Factorized Backprojection Algorithm Integrating with Non-Start-Stop Model for High Resolution SAR Imaging
Using the correct echo model and Cartesian factorized backprojection (CFBP) algorithm, a modified CFBP algorithm is proposed for SAR imaging to improve the accuracy and efficiency of processing.

We develop a linearized imaging theory that combines the spatial, temporal and spectral aspects of scattered waves. We consider the case of fixed sensors and a general distribution of objects, each
