The problem of sniper detection is considered in this work. Audio signals recorded from gunshots by a microphone array are used for estimation of Direction of Arrival of muzzleblast and shockwave components; nevertheless, eventually, there may occur an overlapping of these signals. Algorithms from the Generalized Cross-Correlation (GCC) family are utilized in the DoA estimation, and it is shown that...
Target detection and tracking are the essential functions of modern SONAR systems. Once the direction of arrival is estimated the target is tracked continuously in bearing and the target spectral information is used for classifying the target. A continuous and reliable tracking method is essential for getting the spectral information and classification of the target. Conventional tracking methods...
Depending on the angle of arrivals (AOAs) and other channel characteristics, different types of correlation appear among acoustic pressure and acoustic particle velocity channels. To have accurate channel models for communication system design, a complete set of correlations are derived in this paper for a vector sensor array. In addition to exact results, accurate yet less complex approximations...
The localization of speech sources is critical to the proper functioning of many multiple-microphone devices. Presently, localization algorithms rely on the time-differences-of-arrival (TDOA) to extract the source location from the observed cross-correlation measurements, and view other components (non-direct-path) of the impulse responses as ldquointerference.rdquo In this paper, we propose to employ...
