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 …

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 …

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 …

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 …

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 …

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 …

It is well known that ground moving targets may be smeared in a synthetic aperture radar
(SAR) image due to the range migration, Doppler phase broadening, and velocity ambiguity …

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 …

This letter proposes a new method for focusing ground maneuvering targets and estimating
the motion parameters with a synthetic aperture radar (SAR) system. In this method, the …

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 …
