Automatic Target Recognition for Passive Radar

IEEE Transactions on Aerospace and Electronic Systems, 2014
Air-traffic controllers cannot identify air vehicles flying with a defective or nonexistent transponder. Primary radar does not help, because it cannot classify air vehicles from echoes. Passive radar offers a potential solution, the main difficulty lying in the analysis of the data.

Radar target recognition by fuzzy logic

Proceedings of the 1997 IEEE National Radar Conference, 1998
The objective of this paper is to present a method of target recognition based on the fuzzy logic principles applied to conventional and multifunction radars. After a presentation of the parameters which can be delivered by signal and data processing, the paper gives a description of an algorithm including both spatial and temporal merging. Computation

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 ...

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.

Radar HRRP target recognition with deep networks

Pattern Recognition, 2017
Abstract Feature extraction is the key technique for radar automatic target recognition (RATR) based on high-resolution range profile (HRRP). Traditional feature extraction algorithms usually utilize shallow architectures, which result in the limited capability to characterize HRRP data and restrict the generalization performance for RATR.

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.

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
