Abstract
An apparatus and method for accurately determining the relative locations of sensors in a passive sonar or like monitoring system utilizes two non-parallel (but not necessarily orthogonal) calibrator signals to calculate the relative positions of sensors in a sensor array. Iteration, using a deformed line array constraint, permits reliable solution of the sensor position equations, even when the relative angle between the calibrator signals is initially unknown.
