A SAR-GMTI Approach Aided by Online Knowledge With an Airborne Multichannel Quad-Pol Radar System

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
In the complicated geographical environment, there will be a seriously deleterious effect to the performance of synthetic aperture radar (SAR)-ground moving target indication (SAR-GMTI) system, because it is difficult to obtain the homogeneous training ...

An Interrupted Sampling Scattered Wave Deception Jamming Method against Three‐Channel SAR GMTI

open access: yesMathematical 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

open access: yesInternational 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 ...

Ship Velocity Estimation in Airborne Along‐Track Interferometric SAR Imagery Based on the Fractional Fourier Transform

open access: yesInternational 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 ...
