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 …

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 …

We propose here a new approach for synthetic aperture radar (SAR) imaging of ground
moving targets. The unique characteristic of this approach is that range curvature (ie …

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 …

Ground-moving targets with complex motions often appear seriously dislocated and
smeared in synthetic aperture radar (SAR) imagery due to noncooperative motion …

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 …

In synthetic aperture radar (SAR) images, moving targets are usually smeared and/or
imaged at incorrect positions due to the target motions during the SAR integration time …

With the developments of the synthetic aperture radar (SAR) system, the long dwell time
provides high resolution but at the same time it produces large range migration (RM) and …

Range-Doppler (RD) processing is widely used in conventional inverse synthetic aperture
radar (ISAR) imaging. The unwanted translational motion of moving targets is compensated …

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 …
