Abstract
A passive system for detecting the position and trajectory of a moving body, moving in the air, on the ocean or below the ocean. This apparatus operates by detecting perturbations in the earth's magnetic field responsive to the movement of a body through the field. At least two spaced magnetometers are provided to detect the perturbations of the earth's magnetic field, whereas, the system works more efficiently with an array of sensors. These two sensors are used to filter out the ambient noise. The outputs of these sensors are digitized and inverted through correlation procedures and an output is provided on a display.
