Ground Moving Target Indication in SAR Images by Symmetric Defocusing
IEEE Geoscience and Remote Sensing Letters, 2013A new algorithm is presented to indicate ground moving targets in synthetic aperture radar images. Two filters, which differ only in the signs of the phase responses, are used to defocus the complex image respectively. In the two defocused images, each stationary target is blurred to the same extent, but each moving target is blurred to different ...

Long-CPI Multichannel SAR-Based Ground Moving Target Indication
IEEE Transactions on Geoscience and Remote Sensing, 2016The detection of ground moving targets with arbitrary linear motion from an airborne multichannel radar via a long coherent processing interval is considered. The technique maximizes the target signal energy in synthetic aperture radar (SAR) images by matching to the target's linear motion profile.

Ground Moving Target Indication Based on Optical Flow in Single-Channel SAR
IEEE Geoscience and Remote Sensing Letters, 2019An algorithm based on optical flow is proposed to detect a ground moving target via the single-channel synthetic aperture radar. First, the signal models of uniform moving targets are established and classified into three types. Next, the Doppler spectrum is divided to generate a multilook image sequence.

Sparsity driven ground moving target indication in synthetic aperture radar [PDF]
, 2018 Synthetic aperture radar (SAR) was first invented in the early 1950s as the remote surveillance instruments to produce high resolution 2D images of the illuminated scene with weather-independent, day-or-night performance. Compared to the Real Aperture Radar (RAR), SAR is synthesising a large virtual aperture by moving a small antenna along the platform

IEEE Geoscience and Remote Sensing Magazine, 2020 Along-track interferometric (ATI) synthetic aperture radar (SAR) has proven a powerful tool for ground-moving target indication (GMTI). ATI-SAR systems use more than one antenna (at least two), mounted on a moving platform and displaced along the ...

MIMO SAR based ground moving target indication
2011 Conference Record of the Forty Fifth Asilomar Conference on Signals, Systems and Computers (ASILOMAR), 2011We investigate a framework for the detection of ground moving targets using a Multiple-Input-Multiple-Output (MIMO) radar system. We look at how phase histories collected from a MIMO Synthetic Aperture Radar (SAR) system can be used for target detection in a Ground Moving Target Indication (GMTI) mode while SAR images are being formed.

Ground Moving Target Indication With Tandem Satellite Constellations
IEEE Geoscience and Remote Sensing Letters, 2008Ground moving target indication (GMTI) from space by existing dual-channel radar systems such as TerraSAR-X and RADARSAT-2 has been shown to perform only insufficiently with respect to the relocation error of targets to their true ground position. Only two parallel receiver channels are too little to suppress the severe ground clutter and to estimate ...

Ground moving target indication for MIMO-SAR
2009 2nd Asian-Pacific Conference on Synthetic Aperture Radar, 2009The multi-input multi-output synthetic aperture radar (MIMO-SAR) is an innovative concept, which can bring high degrees of freedom for SAR system with limited transmitting/ receiving (T/R) elements. In this paper, ground moving target indication (GMTI) for MIMO-SAR is studied based on reasonable usage of the space-time equivalent samplings. Furthermore,
