Abstract
The problem of determining whether a line of bearing measured by a local surface-based sensor coincides with a threat whose position has been previously estimated by an ocean surveillance sensor is addressed. Uncertainties in the position estimate of the threat, in the bearing error and in the position estimate of the sensor are considered in measuring the probability that the threat lies on a given bearing from the sensor. A TI-59 calculator program is developed which calculates this likelihood when the threat location density can be assumed to be bivariate normal. Computations required when significant time has elapsed since the original estimate of threat location when the density can no longer be considered bivariate normal are discussed. (Author)
