Maritime Intelligence, Surveillance, Reconnaissance (ISR) and Space Exploitation

This proposal describes the design of an innovative ASW tracking algorithm. It uses data from a high sensitivity magnetometer that is presently being developed under the ONR MMMDS program. This algorithm is called the Magnetic Anomaly Detection (MAD)Tracker Algorithm. It will be incorporated in the Multi-Mode Magnetic Detection System (MMMDS) once it is designed and tested. The outputs of this algorithm are: The three-axis position of the target, the horizontal velocities of the target, the three axisdipole moments of the target and the turns-per-knot of the target. Using the MT Algorithm submarines may be tracked and identified in deep or littoral waters. Fixed Wing, Helicopter or UAV MAD equipped aircraft will be able to track and identify asubmerged target using the MAD Tracker Algorithm. Using a figure eight tracking pattern the ASW aircraft will be able to track after the first two target detections are accomplished. Present ASW aircraft can revisit/detect the submarine using the figureeight MAD pattern every 4 minutes. It is expected that this algorithm will produce positions of the target to less than 100 feet and velocities that are accurate to 0.1 knot. The MT Algorithm will have a variety of commercial and military applications.Although this algorithm's primary focus is tracking and identifying submerged submarine targets in littoral waters, it has a variety of applications in the military and commercial markets. These include: location and characterization of buried mines andUXO, locating and monitoring underground facilities, locating lost submerged ships or aircraft and locating geologic magnetic anomalies that are associated with ore deposits.
