A Novel Method for Sorting Unknown Radar Emitter

2009 International Workshop on Intelligent Systems and Applications, 2009
A new method based on the second dimension of resemblance coefficient (Cr2 ) and the fourth dimension of wavelet packet transform (Wpt4) to improve the sorting correct rate of unknown radar emitter is presented in this paper. The Cr2 and Wpt4 is extracted firstly and used as the sorting basis when the unknown radar emitter signal is received, then the ...

Fractal feature extraction of radar emitter signals

Asia-Pacific Conference on Environmental Electromagnetics, 2003. CEEM 2003. Proceedings., 2003
In this paper, a novel effective approach based on fractal theory is proposed to extract features of radar emitter signals. Box dimension and information dimension are used as classification features to recognize the types of intra-pulse modulation of radar signals.

Radar emitter recognition using intrapulse data

15th International Conference on Microwaves, Radar and Wireless Communications (IEEE Cat. No.04EX824), 2005
Automatic emitter recognition is one of the most difficult tasks in the radar signal analysis. In most cases the modern ESM/ELINT systems cannot recognize the different devices of the same type or class. New method of the radar identification with a very high precision recognizing is the specific emitter identification (SEI).

Radar emitter identification based on EPSD-DFN

2018 IEEE 3rd Advanced Information Technology, Electronic and Automation Control Conference (IAEAC), 2018
Aimed at the problem that the radar emitter characteristic parameters are not fully used in the identification process and the stability of the radar parameter of sample map is not stable enough, the estimation parameter sample diagram (EPSD) is used to describe the characteristic parameter description model of the radar radiant source. A radar emitter

Synthetic Aperture Radar using Emitters of Opportunity

International Journal of Electronics and Telecommunications, 2012
Abstract The capability of a radar imaging system to stay undetected while gathering data is one of the most desired for military reconnaissance systems. This is particularly difficult to achieve for synthetic aperture radar (SAR), that have to emit electromagnetic energy all the time during the operation and to move along a strictly defined route.

Deinterleaving of radar pulses in a dense emitter environment

2003 Proceedings of the International Conference on Radar (IEEE Cat. No.03EX695), 2004
An ESM system consists of a passive radar receiver that receives pulses from the surrounding radars and measures their monopulse parameters, and a deinterleaver that sorts the digital words representing the parameters of theses pulses and groups them in individual radar cells. The parameters of the deinterleaved radar cells are then compared with those

A novel approach for radar emitter signal recognition

The 2004 IEEE Asia-Pacific Conference on Circuits and Systems, 2004. Proceedings., 2005
To enhance recognition rate of radar emitter signals (RESs) to meet the requirements of modem electronic warfare, a novel approach is proposed to recognize automatically different RESs. The main points of the introduced approach include resemblance coefficient feature extraction and support vector machine classifiers. Experimental results show that the

A New Recognition Method of Radar Emitter Signal

Applied Mechanics and Materials, 2013
According to the problem that the existing radar signal recognition method cannot effectively identify the radar signal, a new recognition method based on kernel density estimation is proposed. First using kernel density estimation gets the probability density curve of radar emitter signal parameters, then storing the cures into database as the ...
