Utilization of audio source localization in security systems
Paper deals with utilization of audio source localization in security systems especially dedicated for additional securing of larger objects like squares or military basis for instance. Proposed detection system supposes that intruder makes uniquely determinable noise which can be picked up by microphone array. On the basis of real-time signal analysis from each microphone unit direction to acoustic source can be determined. In this paper is presented time-delay estimation method of the direction of arrival of the sound wave which is used in many other practical applications. Experimental part proposes design of the evaluation system consisting of microphone sensory system and standard personal computer equipped with Advantech PCI-1716 multifunction data acquisition card.
