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

A generalization of DPCA processing for multichannel SAR/GMTI radars
S.560-572This paper generalizes the well-known displaced-phase-center antenna (DPCA) method for efficient ground moving target indication (GMTI) with a two-channel synthetic aperture radar (SAR) to any multichannel SAR/GMTI radars independent of the ...

First Experimental Demonstration of GMTI Improvement Through Antenna Switching
Up to now, theoretical investigations have shown that switching between parts of the transmit and/or receive aperture in a pulse-to-pulse cycle improves the GMTI performance of a two-channel radar system.

An Efficient Imaging Method for Medium-Earth-Orbit Multichannel SAR-GMTI Systems
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.

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 ...
