Directivity index of an underwater acoustic transducer array

  • Thread starter Akshathkrs
  • Start date
In summary, the directivity index of an underwater acoustic transducer array quantifies the efficiency of the array in directing sound waves towards a specific target area while minimizing sound emission in other directions. This index is crucial for optimizing the performance of underwater communication and detection systems, as it influences signal strength, range, and clarity. The design and configuration of the transducer array, along with environmental factors, significantly affect the directivity index, making it a key parameter in underwater acoustics engineering.

Is there a relation or formula to calculate directivity index of an underwater acoustic transducer array, given the half power beamwidths of the array in azimuth and elevation planes.

Welcome to PF.

What have you found so far in your reading? Can you post some links to your reading and ask specific questions about that reading? That's probably the best way to get you started on this question.

Also, do you have any experience with RF antenna arrays? Some of the math will be similar.
