Abstract:

An airborne reconnaissance magnetometer system ARMS was installed in Grumman Tracker S2E aircraft in a joint program with the Naval Air Development Center, Johnsville-Warminster, Pa. Signatures were obtained from targets of special interest and magnetic moments were computed from the flight data and compared with values derived from theoretical considerations. Signal amplitude, noise amplitude, signal period, and relative signal-to-noise ratio were obtained for each signature by passing the recorded signals through a series of half-octave filter steps. Suggestions for optimum filtering are presented. Anti-Submarine Warfare ASW signal processing techniques were investigated to determine their usefulness for land target identification. Applications of the ARMS and EGAD systems and recommendations for future investigations are given.
