It is well known that the motion of a ground moving target may induce the range cell
migration, spectrum spread, and velocity ambiguity during the imaging time, which makes …

In this study, a ground moving target focusing and motion parameter estimation method
based on modified second‐order keystone transform (MSOKT) have been proposed for a …

In this paper, a new algorithm is presented to image ground moving targets and estimate
their motion parameters in a synthetic aperture radar system based on improved axis …

With a long synthetic aperture time, the energy of the ground moving target will be
defocused due to the effect of range migration (RM) and Doppler frequency migration (DFM) …

Ground moving targets may be smeared in a synthetic aperture radar (SAR) image due to
the range migration, Doppler ambiguity and azimuth spectrum split caused by target …

Imaging of a ground moving target (GMT) with synthetic aperture radar (SAR) is a
challenging task, particularly when the Doppler ambiguity happens. This paper proposes a …

Range cell migration (RCM) correction and azimuth spectrum being contained entirely in
baseband are critical for ground moving-target imaging (GMTIm). Without the azimuth …

The image of ground maneuvering targets may be defocused due to the Doppler ambiguity,
high-order range migration (RM), and Doppler frequency migration (DFM) caused by the …

In a synthetic aperture radar (SAR) system, prolonging the integration time can improve the
detection performance of the ground moving target. However, the complex motions of the …

Ground moving targets will typically be defocused because of the range migration (RM) and
Doppler frequency migration (DFM) caused by the unknown relative motions between the …
