Phase‐coded radar waveform design with quantum annealing
IET Radar, Sonar &Navigation, Volume 18, Issue 3, Page 532-540, March 2024.The Integrated Side Lobe Ratio (ISLR) problem the authors consider here consists in finding optimal sequences of phase shifts in order to minimise the mean squared cross‐correlation side lobes of a transmitted radar signal and a mismatched replica.

Intent Inference and Syntactic Tracking with GMTI Measurements [PDF]
IEEE Transactions on Aerospace and Electronic Systems, 2011 In conventional target tracking systems, human operators use the estimated target tracks to make higher level inference of the target behaviour/intent. This paper develops syntactic filtering algorithms that assist human operators by extracting spatial patterns from target tracks to identify suspicious/anomalous spatial trajectories.

A Performance Evaluation of SAR-GMTI Missions for Maritime Applications [PDF]
IEEE Transactions on Geoscience and Remote Sensing, 2015 This paper proposes a new optimized multichannel synthetic aperture radar (SAR) configuration, based on receiving antennas with nonuniformly displaced phase centers, intended for ground moving target indication (GMTI) applications over maritime scenarios. This system is compared with current SAR missions, such as TerraSAR-X (TSX) or TanDEM-X (TDX). The

A Clutter Suppression Approach for SAR-GMTI Based on Dual-channel DPCA
Leida xuebao, 2014 The Displaced Phase Center Antenna (DPCA) technology, a particular form of Space Time Adaptive Processing (STAP), has been widely used in Synthetic Aperture Radar Ground Moving Target Indication (SAR-GMTI).

Multiresolution Signal Processing Techniques for Ground Moving Target Detection Using Airborne Radar
EURASIP Journal on Advances in Signal Processing, 2006 Synthetic aperture radar (SAR) exploits very high spatial resolution via temporal integration and ownship motion to reduce the background clutter power in a given resolution cell to allow detection of nonmoving targets.
