Design of GMTI combining networks
2007 IEEE International Geoscience and Remote Sensing Symposium, 2007 Multichannel radar systems are of choice for ground moving target indication (GMTI) since they allow for a joint space-time processing of the received data that enables an efficient suppression of ground clutter returns. The design of the receiving sensor group is driven by the performance specifications of the intended GMTI modus, which usually ...

Comparison of SAR Based GMTI and Standard GMTI in a Dense Target Environment
SPIE Proceedings, 2006SAR-MTI is a generalization of SAR processing and can work with only a single-phase center. SAR-MTI requires formation of a stack of SAR images assuming different sensor ground speeds. Each image will capture a different set of target velocities, and the complete set of images will focus all target speeds less than a desired maximum speed regardless ...

IEEE Transactions on Geoscience and Remote Sensing, 2022
Motivated by recent advances in deep learning, a novel deep complex-valued convolutional neural network (CV-CNN)-based method is proposed for ground moving target indication (GMTI) in a multichannel synthetic aperture radar (SAR) system. The proposed method integrates the SAR-GMTI task into a blind inverse problem solved by a deep CV-CNN named CV ...

First GMTI Results of the MIRANDA-35 Sensor
IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018 Frequency-modulated continuous-wave (FMCW) synthetic aperture radar (SAR) are nowadays frequently exploited for producing electro-magnetic images of the earth surface. In this paper, we present first ground moving target indication (GMTI) results of the 2016 campaign with the FMCW airborne system MIRANDA-35, and quantify the overall performances.

The tasks of clutter suppression and ground moving target indication are a typical and also very challenging problem for airborne radar systems for both defence and civilian applications. Nowadays, research aims at applying these tasks for passive radar systems on moving platforms.

In addition to imaging, coherent MIMO radars have a strong potential for detecting moving objects and estimating their parameters. This paper investigates different MIMO schemes based on spatial, waveform, and frequency diversity for their GMTI capability.

SPIE Proceedings, 2014
We describe techniques for improving ground moving target indication (GMTI) performance in multi-channel synthetic aperture radar (SAR) systems. Our approach employs a combination of moving reference processing (MRP) to compensate for defocus of moving target SAR responses and space-time adaptive processing (STAP) to mitigate the effects of strong ...
