Description

Automatic bidimensional surveillance and tracking acoustic system (ES2151852). System used for detecting the existence of objects in a surveilled area via acoustic procedures across the audio band 5kHz-20kHz, estimating its dimensional spatial position and recording their trajectories. The operation of the invention is entirely automatic: the operator’s role is reduced to define sensitivity, reach and upgrade speed and launch the master program. In essence, the system includes an A/D and D/A digitization and registry equipment, a set of transducers formed by a structured network of microphones and a speaker, an amplification system and analogic filtering, a real time signal processing unit and a computing unit equipped with the required software for proper functioning of the system.
