    A low cost range-range acoustic positioning system using modified "off-the-shelf" components was developed for use with small manned submarines. Range information is displayed for the submarine pilot and relayed to a microcomputer aboard the surface support vessel. Software developed for the surface-vessel positioning also plots, displays, and records the submarine position. This system was succes... View full abstract»

    Initial testing of the prototype element of a freely drifting infrasonic sensor array is described. The intent of this measurement system is to gather wide aperture data sets which will be used both to characterize ambient noise in the region 1-10 Hz and to assess the gains possible from beam forming utilizing a collection of very low frequency (VLF) sensors. Coherent processing (beam forming) of ... View full abstract»

    Two extensions of the classic passive location problem are considered. The first examines the ranging ability of passive receivers. The second presents alternative ways of describing the geometric content in positioning problems. The implications of the different approaches on the structure and performance of the location receiver are discussed. Because range determination by passive means is miss... View full abstract»

    This paper presents a perspective on contact localization and motion analysis (CLMA) in the ocean environment. Such well-studied cases as passive hearings-only contact motion analysis, multipath ranging, and localization/tracking via arrays are used to illustrate the concept. The performance of current CLMA systems is shown to depend on the type and characteristics of the basic measurements develo... View full abstract»

    Temperature is one of the most frequently measured parameters of the ocean because of its importance to the understanding and prediction of oceanic and meteorological events, and also because the measurement is required for the determination of salinity and density. The ocean temperature range is narrow, -2\deg to 35\deg... View full abstract»

    The problem of associating data with targets in a cluttered multi-target environment is discussed and applied to passive sonar tracking. The probabilistic data association (PDA) method, which is based on computing the posterior probability of each candidate measurement found in a validation gate, assumes that only one real target is present and all other measurements are Poisson-distributed clutte...

  • The effects of array shape perturbation on beamforming and passive ranging

    The problem of beam formation from a towed line array whose shape has been distorted is considered. Emphasis is placed on the beam broadening and range estimation effects of array shape perturbations and how the resulting losses can be regained if the actual element positions are known. Specific illustrations are provided for various levels of shape distortion. For example, a 15-m bow in a 232.5-m... View full abstract»

    A performance prediction procedure is developed and applied to the evaluation of a passive tracking technique intended primarily for the localization of targets in the near field or vicinity of the sensors. The analysis is sufficiently general to be applied to underwater and air acoustics, passive radar, and electromagnetic direction finding systems. Since near field applications are of primary co...

    This paper presents a method for tracking a distant moving target using only bearing measurements obtained from a tracking platform. The method is an improvement of the Hinich-Bloom passive tracking approach presented in [1]. The target is assumed to be moving at constant speed on a fixed heading, whereas the platform maneuvers during the measurement period. The direction cosines of the bearings a... View full abstract»
