Reflections on Selection about Ship Seismic Sensor

Abstract:

In the special marine environmental conditions, there are certain advantages of ship seismic wave relative to underwater acoustic signal. However, due to the poor performance of seismic wave sensor, it is difficult to effectively detect seismic signal. From the signal characteristics of ship seismic wave, we can see that the ship seismic wave signal is better than underwater acoustic signal through comparative analysis in some special environment. In the low frequency band of DC-20Hz, the energy of the ship seismic is stronger and the line spectrum is more obvious. It briefly explains the mathematical model of ocean bottom seismometers receiving ship seismic wave information based on coupling theory. Finally, this paper focuses on many factors need to be considered in the selection of seismic wave sensor from the structure, type and performance of sensor. In view of different functionality of sensor types, it is suggested to use acceleration sensor to detect the ship seismic wave signal.
