Low-frequency vector sensor

Wilcoxon’s vector sensors measure the acoustic pressure and particle acceleration in three orthogonal axes.
These four sensing elements are located in a single housing with a common acoustic phase center. The four channels of the vector sensor, when combined, produce a cardioid directivity pattern which provides approximately 4.8 dB improvement in the signal to noise ratio over a traditional omni-directional pressure sensor. In addition, engineering sensors are embedded within the housing and, when combined with acoustic sensors, can provide a bearing to the target.

  • Three orthogonal axis accelerometers and one omni-directional hydrophone

  • Preamplifier and differential output

  • Micro-controller with RS485 link

  • Power management capability
