This report consolidates some of the work done on the problem of locating objects or targets from line of bearing information. Line of bearing LOB or angle of arrival AoA information is determined by a location and a direction to a target. It is not possible to infer the location of a target from LOB information collected from one site. The simplest case is to infer the location of an object in a plane from two separate measurements. Errors in the measurements result in target location errors. First, through a discussion of errors, the critical features and sensitivities of LOB systems are treated. Following this, a technique for combining more than one estimate of a target location is -discussed. Finally, a system that estimates the trajectory of a target from LOB estimates is examined. Both simulations and closed-form models are used to study LOB system performance. target detection, trajectory estimation, interferometers, line of bearing or angle of arrival.
