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 …

It is well known that the motion of a target induces range migration, especially for high-
resolution synthetic aperture radar (SAR) systems. Ground moving target imaging …

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 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 …

This letter deals with the motion parameter estimation and focusing for ground moving
targets in synthetic aperture radar (SAR) imagery. In the proposed algorithm, after range …

Due to the non-cooperative motion of ground moving targets, they appear smeared and
dislocated in circular synthetic aperture radar (CSAR) imagery. Refocusing of ground …

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 …

Ground-moving targets with complex motions often appear seriously dislocated and
smeared in synthetic aperture radar (SAR) imagery due to noncooperative motion …

Focusing moving targets with frequency-domain algorithms may suffer from azimuth
spectrum not entirely contained within a pulse-repetition frequency band, which may lead to …

In this letter, a novel ground moving target imaging algorithm suitable for high-resolution
synthetic aperture radar (SAR) is proposed. The key step of the proposed algorithm is to …
