Radar automatic target recognition based on InISAR images

2007 1st Asian and Pacific Conference on Synthetic Aperture Radar, 2007
A novel interferometric inverse synthetic aperture radar (InlSAR) imaging method, include an efficient phase unwrapping approach, is proposed, which can work very well under very low signal noise ratio condition. Based on which, an InlSAR image based target recognition method are proposed.

Radar HRRP automatic target recognition: Algorithms and applications

Proceedings of 2011 IEEE CIE International Conference on Radar, 2011
Radar automatic target recognition (RATR) is an important function for modern radar. Target high resolution range profile (HRRP) contains target structure signatures, such as target size, scatterer distribution, etc., thereby radar HRRP target recognition has received intensive attention from the RATR community.

Automatic target recognition based on incoherent radar returns

Proceedings of the IEEE 1995 National Aerospace and Electronics Conference. NAECON 1995, 2002
The problem of reliable automatic target recognition (ATR) from incoherent radar returns is discussed. In the problems under consideration, feature extraction methods are divided into two basic types: (1) Feature extraction directly based on time-domain description; (2) Feature extraction based on multiple transformation technique.

Radar automatic target recognition for alterable noise environment

IET Conference Publications, 2009
Noise level of radar target returned echoes is an essential issue for HRRP automatic target recognition, which will deteriorate recognition performance if test sample have different noise level compared with the training samples. Assuming that HRRP contains additive Gaussian white noise and HRRP signals of range cells are jointly Gaussian-distributed ...

Automatic Recognition of MSTAR Targets Using Radar Shadow and Superresolution Features

Proceedings. (ICASSP '05). IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005., 2006
Automatic target recognition from high range resolution radar profiles remains an important and challenging problem. In this paper, we present a novel feature set for this task that combines a representation of the target's radar shadow with a noise-robust superresolution characterisation of the target scattering centres derived from the MUSIC ...

Survey of radar superresolution methods with applications to automatic target recognition

SPIE Proceedings, 1998
Resolution is a fundamental limitation of any processing based on radar data. Conventional radar imaging techniques, in general, make use of the FFT to determine the spatial location of a target from its scattered field. The resolution of these images is limited by the bandwidth of the interrogating radar system and the aspect angle sector over which ...

A robust algorithm for automatic target recognition using passive radar

Thirty-Sixth Southeastern Symposium on System Theory, 2004. Proceedings of the, 2004
The goal of this research is to add automatic target recognition (ATR) capabilities to existing passive radar systems. We do so by comparing the radar cross section (RCS) of detected targets to the precomputed RCS of known targets in the target class. The precomputed RCS of the targets comprising the target class is modeled using a multi-step process ...
