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 …

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 …

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 an algorithm for airborne synthetic aperture radar (SAR) ground moving
target imaging (GMTIm) and motion parameters estimation (MPE), which is applicable in …

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 …

The synthetic aperture radar (SAR) images of a moving target may be out of focus, given the
motions of a non-cooperative target. Doppler ambiguities, including the Doppler center blur …

In synthetic aperture radar (SAR) imagery, images of ground moving targets (GMTs) are
smeared, distorted, and shifted. Current GMT imaging methods are mostly based on range …

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 …

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 paper deals with the issue of ground moving target imaging and motion parameter
estimation with an airborne dual-channel circular stripmap synthetic aperture radar (CSSAR) …
