DETECTION FERROUS OBJECTS USING LABVIEW

D. Swisulski, M. Woloszyn

Abstract

The ferrous objects disturb evenly distributed Earth magnetic field. It is possible to detect the ferrous objects by measuring the magnetic field. Detection of objects under water in the Baltic Sea is difficult due to large natural magnetic anomalies. In order to eliminate the anomalies, the prediction technique in measurements was used. Before the prediction, the measured signal is filtered to remove unwanted frequencies and this way the object can be detect using a threshold peak detector. LabVIEW was used to simulate the detection of objects in the Baltic Sea.
