A Target Recognition Method of Multi-radar

2008 Fifth International Conference on Fuzzy Systems and Knowledge Discovery, 2008
A target recognition method of multi-radar is proposed based on the kinematical information from multi-radar. The process of target recognition can be divided into three levels. First, air/sea target classification can be obtained based on the information from single radar including target height, velocity, acceleration, elevation rate and azimuth rate

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

Model-catalog compression for radar target recognition

1995 International Conference on Acoustics, Speech, and Signal Processing, 2002
In many model-based automatic target recognition (ATR) systems the size of the model catalog can be a critical factor in determining the viability of the system. We examine an ATR system which uses synthetic high range resolution (HRR) radar data to determine how the classification performance is affected by the compression of the HRR model catalog ...

Radar target recognition using range profiles

Proceedings of ICASSP '94. IEEE International Conference on Acoustics, Speech and Signal Processing, 2002
With the increased availability of coherent wideband radars, there has been a renewed interest in radar target recognition. A large bandwidth gives high resolution in range which means target recognition may be possible. We examine some of the problems of classifying high resolution range profiles (HRRP), and investigate simple preprocessing techniques

Target recognition for marine search and rescue radar

2010 Sixth International Conference on Natural Computation, 2010
The key point of marine search and rescue is to find out and recognize the distress objects. At present, the visual search method is usually adopted to detect the ships in distress, and this method can only be used at good sea condition and visibility. In this paper, a new target detection and recognition system is proposed.

Resolution independent radar target recognition

2011 IEEE RadarCon (RADAR), 2011
The value of Through the Wall Radar Imaging (TWRI) data collected with one system is limited when training the automatic target recognition classifier of a second system because of variation in the Point Spread Function (PSF). The target image is a function of both the scene reflectivity and the PSF, which is in turn a function of the imaging radar's ...

Radar target recognition based on few-shot learning

Multimedia Systems, 2021
With the continuous development of target recognition technology, people pay more and more attention to the cost of sample generation, tag addition and network training. Active learning can choose as few samples as possible to achieve a better recognition effect.

A fractal approach to radar target recognition

Proceedings of International Radar Conference, 2002
A method of radar target classification and recognition through extracting their fractal features directly from the radar echoes is presented. Firstly, two dimensional texture images with distances and directions as the coordinate axes are formed, then, the FFT-Mellin transformation is applied to eliminate the affect caused by flights' motion, posture ...

Correlation target recognition for laser radar

SPIE Proceedings, 2006
The target recognition of laser radar is a hot research because laser radar can produce the intensity and range imagery. Laser radar has high space resolution, and can obtain rich target information. Correlation recognition has been used to many fields, such as infrared as well as synthetic aperture radar (SAR).
