On the identification of β-emitters by absorption measurements

The International Journal of Applied Radiation and Isotopes, 1963
Abstract A method is presented for the identification of pure β-emitters by the determination of the quantity E ∗ = (E 0 + E )/2 characteristic of each radionuclide. The quantity E ∗ is deduced from an empirical relation, E ∗ = E ∗ (μ) , between the values of E ∗ and those of the ...

Cumulants-based Radar Specific Emitter Identification

2011 IEEE International Workshop on Information Forensics and Security, 2011
In this paper we consider the problem of Radar Specific Emitter Identification (SEI) with the aim of distinguishing among several transmitting sources of the same kind which is a very hot topic in the device forensic field. At the design stage, we introduce a classification technique based on some suitable features evaluated from the cumulants of the ...

A hybrid method for classification and identification of emitter signals

2017 4th International Conference on Systems and Informatics (ICSAI), 2017
Communication emitter identification has been recognized as an indispensable task for electronic intelligence system. Recognition of communication emitter signals is presupposition of jamming or striking enemies' equipment effectively in electronic warfare. This paper mainly studies the classification and identification of emitter signals. Firstly, the

Emitter identification based on the structure of unintentional modulation

2016 9th International Congress on Image and Signal Processing, BioMedical Engineering and Informatics (CISP-BMEI), 2016
Unintentional modulation (UIM), which is unavoidable and unique to individual emitters, can be used to reliably realize emitter identification. Previous identification methods extract features from either some parts of the signal, ignoring the UIM on the other parts, or immediately the whole signal, resulting in heavy computational loads. In this paper,

Radiometric Identification of Emitters in the Automatic Identification System

MILCOM 2013 - 2013 IEEE Military Communications Conference, 2013
Radiometric identification of emitters has been attracting attention to reinforce security of wireless systems. It is expected to distinguish subtle differences among emitters even of the same model based only on the measured signals to prevent a fraudulent device from accessing a system.

Specific emitter identification

2008 International Radar Symposium, 2008
The process of final emitter identification is based on ldquothe knowledge-based approachrdquo which was implemented during the processing of constructing the database. The technical and tactical parameters connected with radarpsilas applications are very often a good source of knowledge about the identified emitters.

Specific Emitter Identification using video signals

2012 20th Signal Processing and Communications Applications Conference (SIU), 2012
Specific Emitter Identification(SEI) methods are used in intercept systems for differentiating of same type of emitters in the environment. Most of the SEI implementations are designed for post processing (off line) by operators. This paper presents preliminary results on real time (on line)implementation of a SEI method on signals after the IF stage ...

Specific emitter identification based on amplitude features

2015 IEEE International Conference on Signal and Image Processing Applications (ICSIPA), 2015
This paper describe the Specific Emitter Identification (SEI) technique applied to Electronic Support Measure (ESM) systems. The main idea is to analyze the radar pulses and characterize those by extracting features that should be different for each radar.

The knowledge based approach for emitter identification

12th International Conference on Microwaves and Radar. MIKON-98. Conference Proceedings (IEEE Cat. No.98EX195), 2002
Current Electronic Warfare (EW) systems use algorithmic processing methods which are inflexible and do not fully utilise available sources of a priori information. The EW systems of the future are required to react faster and with greater accuracy to an extremely complex electromagnetic environment.
