A Large Along-Track Baseline Approach for Ground Moving Target Indication Using TanDEM-X [PDF]
, 2007 In the paper a new method for ground moving target indication (GMTI) using two satellites (i.e. the TerraSAR-X and the TanDEM-X satellite) together is presented.

A New Method to Create a Virtual Third Antenna from a Two-Channel SAR-GMTI System [PDF]
, 2007 Two-channel SAR-GMTI systems are suboptimal for moving target motion parameter estimation. Indeed, the ATI phase estimate of the across-track velocity component for a moving target is biased to lower values depending on the target signal to clutter ...

IET Radar, Sonar &Navigation, Volume 18, Issue 9, Page 1431-1443, September 2024.A high precision estimation algorithm for ground moving targets in multi‐channel wide‐area surveillance ground moving target indication systems is proposed based on maximum likelihood method. The main concept of this novel algorithm is to estimate the azimuth angle of the detected targets using maximum likelihood method with the space steering vector ...

Improved moving target detector using sequential combination of DPCA and ATI
The Journal of Engineering, Volume 2019, Issue 21, Page 7834-7837, November 2019., 2019 The detection of moving targets on synthetic‐aperture radar images is one of the most popular approaches to monitor ground vehicles and ships on an ocean. Although the well‐known displaced phase centre antenna (DPCA) or along track interferometry (ATI) has good detection performance, they often produce high false alarm rates. A new scheme, i.e.

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.
