On the effect of SNR and superdirective beamforming in speaker diarisation in meetings [PDF]
, 2012 This paper examines the effect of sensor performance on speaker diarisation in meetings and investigates the use of more advanced beamforming techniques, beyond the typically employed delay-sum beamformer, for mitigating the effects of poorer sensor ...

ATOC-FACT arrival-time differences [PDF]
The Journal of the Acoustical Society of America, 1995 The acoustic thermometry of ocean climate-feasibility ascension Cape Town (ATOC-FACT) propagation experiment took place during November and December of 1992. Explosive charges were detonated near the oceanic sound-channel axis at five locations in the South Atlantic off Cape Town.

A Fractional Programming Method for Target Localization in Asynchronous Networks
IEEE Access, 2018 In this paper, we address the target device localization problem in the asynchronous networks. For the purpose of saving power resources, the target device is not synchronized with the anchor nodes, but is only required to listen to the signals ...

A Two-Stage Method for Short-Wave Target Localization Using DOA and TDOA Measurements
IEEE Access, 2023 The ionosphere can make the short-wave source localization problem further non-linear, leading to a complicated solution process. This paper proposed a coordinated positioning algorithm based on the ionospheric virtual height (IVH) model to jointly ...
