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) …

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 …

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 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 …

This letter studies the issue of ground accelerating target imaging with airborne circular
stripmap synthetic aperture radar (CSSAR). Most of the existing ground moving target …

This letter proposes a fast Doppler parameter estimation and refocusing method for ground
moving targets in a synthetic aperture radar (SAR) system. In the proposed method, after …

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 …

Synthetic aperture radar (SAR) imaging for moving target can obtain complete situational
awareness information of the detection area, and can realize the monitoring and control for …

In synthetic aperture radar (SAR) imaging of a ground moving target, long-time coherent
integration may effectively improve the imaging quality, whereas the imaging performance …

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 …
