Abstract

Abstract

To study the correlation of low-frequency line spectrum characteristics of underwater typical physical fields, an underwater joint measuring device was developed, which integrated the measurement functions of acoustic field, electric field, magnetic field, and pressure field. Secondly, the underwater physical field signals of more than 30 ships with different targets were obtained through tests in a sea area. Finally, based on the measured data, the correlation between the low-frequency (below 100 Hz) line spectrum characteristics of the acoustic field, electric field, magnetic field, and pressure field of typical ships was analyzed. The results show that the line spectrum characteristics of low-frequency pressure signal and low-frequency electric field are strongly correlated and have common sources. The line spectra of the low-frequency acoustic field, pressure field, and low-frequency electric field signal are correlated and have common sources at some frequency points, which provides a new idea for the joint detection and identification of targets based on underwater physical fields.
