Abstract : This report describes work concerned with the detection and determination of the bearing of a single target in an isotropic noise field. In the cases studied, the data source was assumed to be a single hydrophone or a given array of hydrophones. The problems investigated involved studies of likelihood ratio detection of sinusoidal signals in gaussian noise, likelihood ratio detection of gaussian signals in wide-band noise, and determinations of random bearing errors due to processing and also due to medium inhomogeneity for specific types of sonar systems.
