Vector sensors measure the acoustic pressure and particle acceleration in three orthogonal axes. Four sensing elements, located in a single housing with a common acoustic phase center, combine to 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.
