Acoustic Sounding System for Long Range Propagation in Middle East Surroundings.
Abstract
The current report briefly covers the activities carried out during the first interim period. One of the tasks performed was the design and development of the Acoustic Directive Receiver Antenna (ADRA). The main parts of the ADRA namely the microphone array the data acquisition and data processing units have been developed. The ADRA is unitwise functional. A second task performed was the design and development of the Acoustic Power Source (APS) based on standard exponential horn type elements. The horns and associated drivers were selected based on their performance in the low frequency range (50-1000 Hz) . Procurement orders for the APS components have been placed.
