Ground Moving Target Detection With Seismic Fractal Features

IEEE Geoscience and Remote Sensing Letters, 2022
Due to the strong nonstationary characteristics of seismic signals, energy criteria-based methods are not robust for detecting moving targets, especially in data with low SNRs. To address this problem, we propose a new method for detecting ground moving target based on fractal dimension (FD) theory named FD-based support vector machine (FD-SVM).

Data fusion for ground moving target tracking

Aerospace Science and Technology, 2006
The aim of ground surveillance is the large scale, continuous and near real time determination of a dynamical ground picture. This task comprises detection and tracking of moving single targets and convoys, mobile weapon systems, and military equipment.

Detection of moving targets from a moving ground platform

SPIE Proceedings, 2009
Semi-autonomous operation of intelligent vehicles may require that such platforms maintain a basic situational awareness with respect to people, other vehicles and their intent. These vehicles should be able to operate safely among people and other vehicles, and be able to perceive threats and respond accordingly. A key requirement is the ability to

Interferometric moving ground target imaging

Proceedings International Radar Conference, 2002
This paper describes an interferometric synthetic aperture radar (SAR) processing technique, interferometric moving target focusing (IMTF), which is capable of creating clutter suppressed moving ground target images. One-meter range resolution data has been processed and is presented.

Ground moving target processing for tracking selected targets

SPIE Proceedings, 2016
BAE Systems has developed a baseline real-time selected vehicle (SV) radar tracking capability that successfully tracked multiple civilian vehicles in real-world traffic conditions within challenging semi-urban clutter. This real-time tracking capability was demonstrated in laboratory setting.

Imaging of ground moving targets with single-antenna SAR

2015 IEEE China Summit and International Conference on Signal and Information Processing (ChinaSIP), 2015
In this paper, a novel method is proposed for the imaging of ground moving target with motion error compensation. The Keystone and Hough transform are utilized to correct the Range Cell Migration first. Then the Fractional Fourier transform (FrFT) is adopted to estimate the Doppler parameters of ground moving targets. Finally, moving targets are imaged.
