Automatic target recognition using waveform diversity in radar sensor networks

Pattern Recognition Letters, 2008
In this paper, we perform a number of theoretical studies on constant frequency (CF) pulse waveform design and diversity in radar sensor networks (RSN): (1) the conditions for waveform co-existence, (2) interferences among waveforms in RSN, (3) waveform diversity combining in RSN. As an application example, we apply the waveform design and diversity to

LDGAN: A Synthetic Aperture Radar Image Generation Method for Automatic Target Recognition

IEEE Transactions on Geoscience and Remote Sensing, 2020
Under the framework of a supervised learning-based automatic target recognition (ATR) approach, recognition performance is primarily dependent on the amount of training samples. However, shortage in training samples is a consistent issue for ATR. In this article, we propose a new image to image generation method, called label-directed generative ...

Multiview Synthetic Aperture Radar Automatic Target Recognition Optimization: Modeling and Implementation

IEEE Transactions on Geoscience and Remote Sensing, 2018
Multiview synthetic aperture radar (SAR) images could provide much richer information for automatic target recognition (ATR) than from a single-view image. It is desirable to find optimal SAR platform flight paths and acquire a sequence of SAR images from appropriate views, so that multiview SAR ATR can be carried out accurately and efficiently.

Automatic target recognition in laser radar imagery

1995 International Conference on Acoustics, Speech, and Signal Processing, 2002
This paper presents an automatic target recognition (ATR) system for laser radar (LADAR) imagery, designed to classify objects at multiple levels of discrimination (target detection, classification, and recognition) from single LADAR images. Segmentation is performed in both the range and non-range LADAR channels and results combined to increase object

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.
