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 …

The problem of ground moving target imaging and detection is difficult due to the large
range cell migration (RCM) and time-varying Doppler frequency migration (DFM) in synthetic …

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 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 …

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 …

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) …

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 …

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 …

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 …
