Abstract:Recently, the need to monitor restricted areas has increased. Acoustics is one of the available key techniques, but there are some restrictions and constraints to consider. In situations with unknown noise and low SNR the performance of time delay based direction of arrival (DOA) estimators collapses rapidly as SNR decreases. Outliers are introduced into estimation results when signals of interest are masked by noise.There exist several methods for compensation of noise induced errors, such as averaging within… Show more
