Detection of RF Electronics by Multitone Harmonic Radar
IEEE Transactions on Aerospace and Electronic Systems, 2014Multitone harmonic radar is presented. The radar transmits multiple closely-spaced tones and receives nonlinear mixing products as well as harmonics. Harmonic and multitone responses are recorded from commercially-available RF devices. An original method for discriminating between electronic targets, by receiving at least two nonlinear mixing products ...

Harmonic signals are often produced by man-made sources. Their detection has traditionally been accomplished by using Fourier methods. An alternative approach that uses a maximum likelihood function is presented in this paper. The power of this approach comes from modelling the received signal as a family of harmonic signals.

We examine the detection problem of signals with narrowband, harmonically related components received by a passive sensor array. We investigate detector structures based on the Fourier method. The harmonic detector estimates the total signal power by combining the DFT coefficients from harmonic frequency bins.

Detection of a mistuned component in a harmonic complex
The Journal of the Acoustical Society of America, 1994The ability to detect a mistuned component in a harmonic complex was measured as a function of harmonic number using three different stimulus procedures. The harmonic complex and target component were presented either simultaneously to the same ear (simultaneous monotic), successively to the same ear (successive monotic), or simultaneously to different

Pitch detection using harmonic histograms
Speech Communication, 1982Abstract A method of detecting the pitch frequency of voiced speech is described, which exploits the harmonic structure of the short-time spectrum. The technique is to form a harmonic histogram. Pitch is then detected as the frequency of the largest component.

Harmonic detection using wavelet transform
Proceedings. 2005 IEEE International Joint Conference on Neural Networks, 2005., 2006Power quality is increasingly becoming a major concern due to excessive use of sensitive equipments. Determining the cause of power quality disturbances using various approaches such as neural network and expert system becomes essential in order to take suitable corrective action. In this paper, wavelet transform is proposed to identify the predominant

Harmonic detection by using neural network
Proceedings of ICNN'95 - International Conference on Neural Networks, 2002A methodology of harmonic detection in active power filter from the power line by using neural network is presented. Harmonic detection by using Fourier transformation is an advantageous method to compensate a specific harmonic component. However, it needs input data for each cycle of the current waveform and needs time for the analysis in each cycle ...
