Abstract
The use of passive sensors to estimate range and bearing to an acoustic source is investigated. The variance of the estimators is shown to depend on the number of sensors, integration time, signal-to-noise ratio, and more significantly, on the available array length. The variances for four different array configurations are discussed.Keywords
