Multichannel SAR-GMTI in Maritime Scenarios With F-SAR and TerraSAR-X Sensors
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2015 This paper explores the ground moving target indication (GMTI) capabilities of the German Aerospace Center’s state-of-the-art airborne (F-SAR) and spaceborne (TerraSAR-X) synthetic aperture radars (SARs) when operating over maritime scenarios.

The detection and tracking of ground moving vehicles from airborne radar can be challenging at slow target velocities due to the close space-time (angle-Doppler) proximity of strong competing mainbeam clutter. Moreover, in complex non-stationary clutter environments, conventional space-time adaptive processing (STAP) cannot be relied upon to provide ...

The Influence of Target Micromotion on SAR and GMTI
IEEE Transactions on Geoscience and Remote Sensing, 2011This paper analyzes the influence of typical target micromotions on synthetic aperture radar (SAR) images, azimuth resolution limit, SAR/ground moving target indication (GMTI), and MTI. According to the micromotion periods contained in the coherent processing interval, a new range model expansion and a generalized paired echo principle are proposed and

The Influence of Rebound Jamming on SAR GMTI
IEEE Geoscience and Remote Sensing Letters, 2015Ground moving-target indication (GMTI) has been extensively used in the measuring of ocean surface currents and ground traffic. The influence of rebound jamming on synthetic aperture radar (SAR) GMTI is studied in this letter. The rebound jamming signal is either deceptive or barrage jamming according to the time delay. When the time delay between each

A simulation framework for testing GMTI trackers
2010 13th International Conference on Information Fusion, 2010Trackers for Ground Moving Target Indicator (GMTI) radar have to be benchmarked in order to yield good results. For many benchmarking purposes, the usage of real data may become expensive and in-feasible. It may also lack of knowledge of the ground truth. Simulating GMTI situations is a less-expensive alternative to real measurements. In order to get a

Practical Dynamic Logic GMTI Tracker
2007 International Joint Conference on Neural Networks, 2007Dynamic logic (DL) method provides an efficient algorithm for tracking targets in clutter. The DL tracker overcomes the combinatorial complexity of tracking by substituting the discrete assignment problem with a problem of continuous optimization of the maximum likelihood criterion in a low-dimensional parameter space. DL enables efficient optimization

We consider ground moving target indication (GMTI) and target velocity estimation based on multi-channel synthetic aperture radar (SAR) images. Via forming velocity versus cross-range images, we show that small moving targets can be detected even in the presence of strong stationary ground clutter.

Analytical SAR-GMTI principles
SPIE Proceedings, 2016This paper provides analytical principles to relate the signature of a moving target to parameters in a SAR system. Our objective is to establish analytical tools that could predict the shift and smearing of a moving target in a subaperture SAR image.

Change Detection and Signature Classification for SAR GMTI
IGARSS 2020 - 2020 IEEE International Geoscience and Remote Sensing Symposium, 2020The pursuit monostatic is a SAR operating mode that requires two SAR data acquisitions separated in short time (seconds) using the same flight tracks and being. In this case, the changes in a SAR scene come mainly from ground moving targets, thus opening up opportunities to detect ground moving targets using SAR change detection methods.
