Impact of PRF design on GMTI performance of MIMO-SAR for hypersonic platform with curved trajectory
The Journal of Engineering, 2019 Compared with the conventional single-channel sampling or azimuth multichannel sampling of SAR system, the multiple-input multiple-output (MIMO) sampling has the potential to realise the high-resolution wide swath (HRWS) imaging and the ground moving ...

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 ...

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 ...

Performance limits for exo-clutter Ground Moving Target Indicator (GMTI) radar. [PDF]
, 2010 The performance of a Ground Moving Target Indicator (GMTI) radar system depends on a variety of factors, many which are interdependent in some manner. It is often difficult to 'get your arms around' the problem of ascertaining achievable performance limits, and yet those limits exist and are dictated by physics.
