| description | ObjectiveThis paper aims to evaluate the impact of flow-induced vibration on the receiver performance of low-frequency magnetic antenna in an underwater environment, investigating the electromagnetic-induced noise of antenna under different vibration conditions. MethodsFirst, a fluid excitation antenna vibration model is established using COMSOL software, then an antenna vibration-induced noise model is constructed to simulate electromagnetic-induced noise. Finally, outdoor experiments to measure the antenna vibration-induced noise are carried out. Results The results show that the stronger the antenna vibration is, the greater the electromagnetic-induced noise is. When the antenna vibration acceleration reaches 0.029 4 m/s², the electromagnetic-induced noise above the pT level will be caused, and the normal communication signal will be submerged. ConclusionThe results show that the proposed model in this paper can be used to evaluate the vibration-induced noise of low frequency magnetic antenna. |
