Abstract :
The authors address the problems encountered in the realisation of a practical time delay beamformer for the reception of acoustic data transmitted through the water. They outline a solution that employs significantly less hardware than that used by other reported schemes, and does so without sacrificing beam pattern integrity. Results obtained from outdoor tests are also presented
