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 …

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 …

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 …

The synthetic aperture radar (SAR) image of moving targets will defocus due to the unknown
motion parameters. For fast-maneuvering targets, the range cell migration (RCM), Doppler …

The synthetic aperture radar (SAR) image of ground moving target is easily defocused given
the unknown relative motions between radar and target. In addition, the limitation of pulse …

A new ground moving target focusing method for airborne synthetic aperture radar (SAR) is
introduced in this paper. Firstly, first-order discrete polynomial-phase transform (DPT) is …

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 …

This letter proposes an algorithm for airborne synthetic aperture radar (SAR) ground moving
target imaging (GMTIm) and motion parameters estimation (MPE), which is applicable in …

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 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 …
