Summary of Field Work: |
We propose to demonstrate long range acoustic communications between a towed acoustic source and a towed hydrophone array. |
|
Summary of Facility Requirements: |
Two ships are required. One ship will tow an acoustic sound source and the other ship will tow an acoustic horizontal receive array. |
