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 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 …

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 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 …

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 …

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 …

The imaging quality and efficiency are equally important in inverse synthetic aperture radar
(ISAR) imaging. The high-order spatial variant (SV) phase errors induced by the target's …

The synthetic aperture radar (SAR) image of moving targets will defocus due to the unknown
motion parameters. For fast-maneuvering targets, the range cell migration (RCM), Doppler …

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) …
