Automatic radar target recognition of objects falling on railway tracks

Measurement Science and Technology, 2012
This paper presents an automatic radar target recognition procedure based on complex resonances using the signals provided by ultra-wideband radar. This procedure is dedicated to detection and identification of objects lying on railway tracks. For an efficient complex resonance extraction, a comparison between several pole extraction methods is ...

Using the Amplitude Fluctuation Property of Target HRRP for Radar Automatic Target Recognition

2006 CIE International Conference on Radar, 2006
Due to the aspect sensitivity of high-resolution range profile (HRRP), traditional radar HRRP target recognition methods usually use average profile within some target-aspect region as the target-aspect template. Actually, the amplitude fluctuation property of target HRRP also represents some feature information of the target.

Exploitation of target shadows in synthetic aperture radar imagery for automatic target recognition

SPIE Proceedings, 2006
The utility of target shadows for automatic target recognition (ATR) in synthetic aperture radar (SAR) imagery is investigated. Although target shadow, when available, is not a powerful target discriminating feature, it can effectively increase the overall accuracy of the target classification when it is combined with other target discriminating ...

(Automatic) target detection in synthetic aperture radar imagery via terrain recognition

Proceedings 2001 International Conference on Image Processing (Cat. No.01CH37205), 2002
Surveillance of large areas of the Earths surface is often undertaken with low resolution synthetic aperture radar (SAR) imagery from either a satellite or a plane. There is a need to process these images with automatic target detection (ATD) algorithms.

High Resolution Radar Automatic Target Recognition Based on an Improved LDA Method

2008 Fifth International Conference on Fuzzy Systems and Knowledge Discovery, 2008
A novel improved linear discriminant analysis (ILDA) method is presented. Comparing with LDA, under the condition of d < c -1, d and c are the dimensionality of feature subspace and the number of classes respectively, ILDA uniformly preserves the class distances of classpairs by rearranging the contribution of each class-pair to the generalized between-

Automatic target recognition using sequences of high resolution radar range-profiles

IEEE Transactions on Aerospace and Electronic Systems, 2000
In this paper, we address the problem of joint tracking and recognition of a target using a sequence of high resolution radar (HRR) range-profiles. The likelihood function for the scene configuration combines a dynamics-based prior on the sequence of target orientations with a likelihood for range-profiles given the target orientation.
