Detection of ground moving targets in COSMO-SkyMed SAR images

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
The aim of this work is the development of processing techniques in order to provide the Cosmo-SkyMed (CSK) single-channel SAR system of Ground Moving Target Indication (GMTI) capabilities. To this purpose a two step processing chain is proposed: the first step performs stationary clutter suppression while the second step performs moving targets ...

Detection and Imaging of Ground Moving Targets With Real SAR Data

IEEE Transactions on Geoscience and Remote Sensing, 2015
Detection and imaging of multiple moving targets is a challenging task, particularly with real synthetic aperture radar (SAR) data. In this paper, moving targets with different motion parameters are classified based on the relative locations of their spectra to that of the clutter.

Minimum Divergence Approaches for Robust Classification of Ground Moving Targets

IEEE Transactions on Aerospace and Electronic Systems, 2012
This work addresses the problem of automatic target recognition (ATR) using micro-Doppler information obtained by a low-resolution ground surveillance radar. Gaussian mixture models (GMMs) are used to represent the prior statistical information of threatening ground moving targets such as walking personnel and tracked or wheeled vehicles.

Ground Moving Target Indication in SAR Images by Symmetric Defocusing

IEEE Geoscience and Remote Sensing Letters, 2013
A 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 ...

Track segment association for ground moving targets with evasive move-stop-move maneuvers

SPIE Proceedings, 2010
In a real tracking system, track breakages can occur due to highly maneuvering targets, low detection probability, or clutter. Previously, a track segment association approach (TSA) was developed for an airborne early warning (AEW) system to improve track continuity by"stitching" broken track segments pertaining to the same target.

Ground Moving Targets Imaging Algorithm for Synthetic Aperture Radar

IEEE Transactions on Geoscience and Remote Sensing, 2011
It is well known that the motion of a target induces range migration, especially for high-resolution synthetic aperture radar (SAR) systems. Ground moving target imaging necessitates the correction of the unknown range migration. To finely refocus a moving target, one must accurately obtain the motion parameters for compensating the target trajectory ...

Efficient detection of ground moving targets in FMCW SAR by focusing

2015 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2015
Frequency-Modulated Continuous-Wave Synthetic Aperture Radar (FMCW SAR) is a compact promising remote imaging sensor. Providing FMCW SAR system with simultaneous GMTI application is an appealing and difficult work. To discriminate the target optimally, the total moving target range walk must be taken in account, especially considering its high ...

Separating Ground-Moving Targets from Clutter

1998
In this chapter, after briefly examining the problem, we will be introduced to two highly effective techniques for detecting such targets. One is called Classical DPCA, for displaced phase center antenna. The other and newer technique are called notching or clutter nulling. We'll take up Classical DPCA first; then, notching; and, finally, a combination

Ground Moving Target Indication and Imaging in WAS Mode

2017
This chapter mainly discusses the GMTI and GMTIm algorithms in WAS mode. The signal mode of moving target is established in WAS mode, and a new system design scheme is presented to maintain the sharpening ratio constant without increasing the system and signal processing complexity.
