Interaural coherence for noise bands: Waveforms and envelopes [PDF]

open access: yesThe Journal of the Acoustical Society of America, 2010
This paper reports the results of experiments performed in an effort to find a formulaic relationship between the interaural waveform coherence of a band of noise γW and the interaural envelope coherence of the noise band γE. An interdependence described by γE=π/4+(1−π/4)(γW)2.1 is found.

A combined denoising method of empirical mode decomposition and singular spectrum analysis applied to Jason altimeter waveforms: A case of the Caspian Sea

open access: yesGeodesy and Geodynamics, 2022
During the satellite pulse propagation and reception, the altimeter waveform is inevitably affected by noise. To reduce the noise level in Jason altimeter waveforms, we used singular spectrum analysis (SSA), empirical mode decomposition (EMD), and the ...

Parameter estimation for peaky altimetric waveforms [PDF]

open access: yes, 2013
Much attention has been recently devoted to the analysis of coastal altimetric waveforms. When approaching the coast, altimetric waveforms are sometimes corrupted by peaks caused by high reflective areas inside the illuminated land surfaces or by the ...

The electromagnetic performance of brushless permanent magnet DC motors - with particular reference to noise and vibration. [PDF]

open access: yes, 1991
A comprehensive analytical technique is developed for predicting the instantaneous magnetic field distribution in radial-field, surface-mounted permanent magnet brushless DC motors under any load condition and commutation strategy.

Jammer-Nulling Transmit-Adaptive Radar Against Knowledge-Based Jammers in Electronic Warfare

open access: yesIEEE Access, 2019
The authors present transmit-adaptive jammer nulling waveforms in cognitive radar (CRr) for aircraft response recognition as a form of electronic support in the electronic warfare domain. New forms of knowledge-based noise jammers that function as a form

Corn plants as temporary acoustic barrier to limit the effects of noise pollution

open access: yes, 2021
Corn is a cereal imported into Europe from the Americas. It is used for human and animal feed, but there are also industrial uses such as the production of ethanol, of fuel for heating homes, or the production of starch. Corn grows in the summer in areas

Performance of Generalized Multicarrier DS-CDMA Using Various Chip Waveforms [PDF]

open access: yes, 2003
In this letter, we extend our investigation of generalized multicarrier direct-sequence code-division multiple access by considering two additional types of chip waveforms, namely, the time-domain half-sine and raised-cosine chip waveforms, in addition ...

Counter-Interception and Counter-Exploitation Features of Noise Radar Technology

open access: yesRemote Sensing, 2021
In defense applications, the main features of radars are the Low Probability of Intercept (LPI) and the Low Probability of Exploitation (LPE). The counterpart uses more and more capable intercept receivers and signal processors thanks to the ongoing ...

Direction detector for distributed targets in unknown noise and interference [PDF]

open access: yes, 2013
Adaptive detection of distributed radar targets in homogeneous Gaussian noise plus subspace interference is addressed. It is assumed that the actual steering vectors lie along a fixed and unknown direction of a preassigned and known subspace, while ...
