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 …

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 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 …

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 …

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 …

The unknown relative motions between synthetic aperture radar (SAR) and a ground moving
target will lead to serious range cell migration (RCM) and Doppler frequency spread (DFS) …

Unknown motions will make the synthetic aperture radar (SAR) images of ground moving
targets defocused. The target signal easily exhibits Doppler ambiguity due to the limitation of …

In this paper, we address the detection and motion parameter estimation problem for a
maneuvering target with complex motions, where range migration (RM, including range walk …

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 …

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 …
