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 in a synthetic
aperture radar (SAR) system based on range frequency reversal transform-fractional Fourier …

In a conventional synthetic aperture radar (SAR) image, a moving target may be smeared
and displaced. Taking direct action on the defocused region of interest (ROI) data from the …

In this paper, a parametric sparse representation (PSR) method is proposed for refocusing of
moving targets in synthetic aperture radar (SAR) images. In regular SAR images, moving …

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 …

Ground-based synthetic aperture radar (GBSAR) has the advantage of retrieving
submillimeter deformation of the mine slope by using the differential interferometry …

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 …

This paper proposes a new method to focus a ground moving target with complex motions
and estimate its motion parameters in a synthetic aperture radar (SAR) system. In this …

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 …

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) …
