Kronecker STAP and SAR GMTI [PDF]
SPIE Proceedings, 2016 As a high resolution radar imaging modality, SAR detects and localizes non-moving targets accurately, giving it an advantage over lower resolution GMTI radars. Moving target detection is more challenging due to target smearing and masking by clutter.

An Interrupted Sampling Scattered Wave Deception Jamming Method against Three‐Channel SAR GMTI
Mathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020 An important problem is how to generate false moving targets, whose relocated azimuth position is similar to that of real moving targets. To solve this problem, an interrupted sampling scattered wave deception jamming method against three‐channel synthetic aperture radar ground moving target indication (SAR GMTI) is proposed. A stationary jammer uses a

Imaging Algorithm for Sea‐Surface Ship Targets Based on Block Sparsity
International Journal of Antennas and Propagation, Volume 2020, Issue 1, 2020., 2020 In this study, a phased array radar was used to accurately image stationary and moving ship targets on the vast sea surface. To solve the challenge in real‐time processing of the massive amount of data generated by phased array synthetic‐aperture radar imaging, this study leveraged the block sparse characteristics of ships on the sea surface and ...

An Efficient Imaging Method for Medium-Earth-Orbit Multichannel SAR-GMTI Systems
Remote Sensing, 2022 Medium-Earth-orbit (MEO) synthetic aperture radar (SAR) has the advantages of short revisit time and wide coverage, and thus is a potential tool for implementing ground moving target indication (GMTI) tasks.

International Journal of Antennas and Propagation, Volume 2020, Issue 1, 2020., 2020 Synthetic aperture radar (SAR) was originally exploited to image stationary scenes. However, it is important to derive target information of velocity for many applications. The fractional Fourier transform (FrFT) is a generalization of the classical Fourier transform and is well‐known as a useful tool to estimate the chirp rate of linear frequency ...

Detection of Road Foreign Body Intrusion with Synthetic Aperture Radar
Mathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020 Foreign body intrusion will cause interruption of road transportation and bring great threat to operation safety. Detection of foreign body intrusion is a key step for efficient recognition, location, and tracking of foreign body intrusion. Current detection approaches of foreign body intrusion are available, but can only detect in a certain range.
