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

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 a multichannel synthetic aperture radar (SAR) system, because of the target
uncooperative motion, a ground moving target (GMT) is usually smeared, distorted, and …

In synthetic aperture radar (SAR), long integration time may induce range migration and
Doppler frequency migration of a received signal, which may degrade the SAR imaging …

High speed, high maneuverability, and weak space-moving targets (SMTs) are major threats
for space-borne radar (SBR) systems. First, the severe range migration (RM) and Doppler …

Imaging of ground multiple moving targets in a synthetic aperture radar (SAR) system is a
challenging task due to the fact that targets are defocused owing to motions and …

Synthetic aperture radar (SAR) image formation for a ground moving target necessitates the
compensation of the unknown target trajectory. The keystone transform has been employed …

Detection and imaging of multiple moving targets is a challenging task, particularly with real
synthetic aperture radar (SAR) data. In this paper, moving targets with different motion …

In this letter, a synthetic aperture radar (SAR) data reformatting approach named Doppler
keystone transform (DKT) is proposed to correct the range migration of a moving target. By …

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 …
