Implementation of a low-cost system and software, based on a Not-Uniform
Linear Array is possible;
Good agreement between the estimated and theoretical values of array
directivity.
Good capability of the system to detect real angle of incoming sound
(DOA), especially at medium-high frequencies (greater directivity). (Passive sonar)
Identification of submerged objects placed in a wide angle under the
array is possible. (Active sonar)
The linear sine sweep shows high SNR, high immunity to external noise and
good capability to penetrate in the sediments.
Conclusion
Future Work
