This paper proposes a new method to focus a ground moving target with complex motions
and estimate its motion parameters in a synthetic aperture radar (SAR) system. In this …

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 …

Long synthetic aperture time can improve the imaging quality of a ground moving target,
whereas a moving target may be severely smeared in the cross-range image due to 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 …

This letter proposes a novel algorithm for focusing moving targets with fast cross-track
velocities and estimating their motion parameters with single-antenna synthetic aperture …

In recent years, ground moving target imaging in synthetic aperture radar (SAR) has
attracted the attention of many researchers all over the world. A novel approach is proposed …

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 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 …

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 …
