Acoustic Detection of Speaker Position Using Microphone Array
Pelz, Zdeněk ; Novotný, Ondřej (referee) ; Szőke, Igor (advisor)
This thesis explores problematics of speaker localization using microphone array. Aim of this thesis is implementation of algorithms for speaker localization and experiments with those algorithms. Calculation of TDOA was done using cross-correlation and hyperbolic method was used to calculate position estimation. Finished microphone array is able to locate speaker within certain variance. Results of this thesis allow reader to make assumptions regarding accuracy of localisation using microphone array and ARM kit with limited performance. Precision of position estimation using microphone array reached several decimeters, but this precision is dependent on distance from microphone array.

Acoustic Drone Detection Using Microphone Array
Múčka, Milan ; Beran, Vítězslav (referee) ; Szőke, Igor (advisor)
This work deals with methods of acoustic localization for electrical multicopters using a microphone field composed of several microphones at a certain distance. The main methods of localization and detection using sound waves are explained in the paper. Next, the algorithms that implement these methods are designed. The results summarize the results of these algorithms together with experiments to verify their functionality.
