Glenville Dr. Suite 116 Richardson, Texas 75081-1954 Contact: Douglas McGregor Phone: (972) 690-0099 Web Site: polatomic.com Abstract: This SBIR Phase I proposal describes the development of a conceptual design for Matched-field Gradiometer Processing (MGP) for ASW, an advanced processing approach capable of taking advantage of recent and pending advances in ultra high-sensitivity scalar laser magnetometer development for airborne and undersea ASW. This matched-field approach to magnetic gradiometer processing for magnetic anomaly detection in ASW systems will provide unprecedented precision in magnetic noise reduction, detection, target parameter extraction, localization, and prosecution/tracking. Under this SBIR project, the processing of magnetic sensor data will be defined to provide target information and identification never before accomplished in real-time operation. Advanced noise reduction methodology will be developed to improve and enhance detection and localization of sea and land targets. Under this Phase I Project, the feasibility of implementing this advanced algorithm for operational use in Phase II will be established. Benefits: Matched-field Gradiometer Processing can provide an unparalleled advance in a variety of commercial and military applications including measurement of the magnetic fields in the human body. Moreover, MGP can also be used with an ELF communications receiver. Superior noise reduction and signal component extraction capabilities of the MGP, in conjunction with high sensitivity advanced magnetometers, make possible high performance, short or long baseline gradiometers for use at the Earth's surface in airborne and surface geomagnetic prospecting as well as unexploded ordinance detection (UXO). MGP complements the laser magnetometer technology currently being developed by the US Navy for submarine detection and mine countermeasures applications. MGP will produce highly accurate and complete parametric signature analysis of magnetic signals detected for a variety of applications in commercial security and surveillance applications. Furthermore, MGP is ideal for geological exploration and mapping, underground and undersea cable/pipe location, archeology, earthquake prediction, biomedical, manufacturing quality control, and law enforcement.
