Abstract

The Phase II effort consists of a 12-month Base and two 6-month Options. The Base is centered on the design, fabrication, and test of a prototype projector and power electronics. Testing is planned at NUWC Seneca Lake to evaluate the projector s electro-acoustic performance. The first Option is geared on the design, fabrication, and test a prototype acoustic communication system that relies on the hardware developed during the Base. Testing is planned at NSWC Lake Pend Oreille to evaluate the communication system s performance resulting from the transmission of PRN, BPSK, and QPSK waveforms. The second Option considers a system engineering study to transition the prototype communication system for use at the Aloha Cabled Observatory located 100 km from Oahu, HI.
