Abstract:

This report covers a continuation of work described in PSR Report 2474. In the earlier study it became apparent that a great portion of the variability of the magnetic anomaly signatures stemmed not from the submarine-centered anomaly itself but rather from the path of the airborne magnetometer through the anomaly. Accordingly, this study focused on the anomaly in target-fixed coordinates, revealing the lobe structure of the anomaly, which, in turn, enabled a clearer understanding of the signatures produced by an airborne magnetometer. Additionally, temporal and spatial dependencies of magnetic anomalies from modulated galvanic currents were determined in both target-fixed and sensor-fixed coordinates.
