Study on optimal calculation of magnetic sensor network to be used to determine from magnetic signatures of military ships

Abstract

In the military ship's magnetic anomaly detection devices, the magnetic field sensor is the most important component, which directly affects the detection ability and accuracy of the heteromagnetic measurement results. These sensors are usually of the high-sensitivity type, using cores of materials that respond very strongly to external magnetic fields. When placed close enough together, these sensors have the potential to interact with each other and cause measurement results to be erroneous. This paper presents the results of research on optimal calculation of 1D and 2D array distribution distances of a magnetic sensor, with the goal of minimizing the mutual influence of sensors placed close together, namely small than the sensitivity of the sensors themselves. The expected result is to determine the optimal distance corresponding to the optimal number of sensors, enough to assume that there is no influence on the magnetic field between neighboring sensors.
