A Space-Time Adaptive Processing Method Based on Sparse Reconstruction of Reverberation Interference
Aiming at the problem of how to obtain reverberation samples and estimate their covariance matrix in the space-time adaptive processing(STAP) of sonar system, a new space-time adaptive processing method is proposed based on sparse reconstruction of ...

Recall of Reverberant Speech in Quiet and Four-Talker Babble Noise
Using behavioral evaluation of free recall performance, we investigated whether reverberation and/or noise affected memory performance in normal-hearing adults. Thirty-four participants performed a free-recall task in which they were instructed to repeat

Central Masses and Broad-Line Region Sizes of Active Galactic Nuclei. II. A Homogeneous Analysis of a Large Reverberation-Mapping Database [PDF]
We present improved black hole masses for 35 active galactic nuclei (AGNs) based on a complete and consistent reanalysis of broad emission-line reverberation-mapping data.

Diffuse reverberation is ultrasound image noise caused by multiple reflections of the transmitted pulse before returning to the transducer, which degrades image quality and impedes the estimation of displacement or flow in techniques such as elastography

Abstract In the Colombian peace referendum, the 2016 accord with the FARC guerrilla, which sought to end fifty years of war, was rejected by 50.2% of voters. The referendum created new identity divides between ‘Yes’ and ‘No’ voters, product of political “narrative wars” which intersected with ...

Research on reverberation characteristics analysis and suppression methods for active continuous detection [PDF]
Compared with the traditional active detection with monopulse periodic emission mode, active continuous detection has the advantages of large emission duty ratio and continuous acquisition of process information.

Simulation of sonar reverberation signal considering the ocean multipath and Doppler effect
In order to achieve accurate modeling and simulation of sonar reverberation signals, four types of multi-path underwater reverberation models are established considering Doppler effect under the condition of separating the sound source and hydrophone ...

Multi-timescale reverberation mapping of Mrk 335 [PDF]
Time lags due to X-ray reverberation have been detected in several Seyfert galaxies. The different traveltime between reflected and directly observed rays naturally causes this type of lag, which depends directly on the light-crossing time-scale of the
