Correcting the range migration of moving targets and compensating for the coupled phase
errors are crucial for ground moving target imaging (GMTIm). Most methods achieve target …

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 …

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 …

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 …

Refocusing ground manoeuvring targets with complex motions in synthetic aperture radar
(SAR) remains a challenging objective because of the large range of cell migration (RCM) …

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 …

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 …

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 …

In this paper, a new method is proposed to refocus a ground moving target in synthetic
aperture radar imagery. In this method, range migration is compensated in the 2-D …

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 …
