Advanced Acoustic Concepts (AAC) will develop a spread spectrum waveform for use with the existing receive-only sonobuoys. Ideally the sonar source will be constructed to operate at 100% duty-cycle. This is an ideal application for a spread spectrum waveform as the largest reduction in transmit power is achieved using the highest pulse compression which in turn is achieve through use of very high duty cycle waveforms. AAC will provide analysis of system performance in reverberation, acoustic intercept vulnerability, and processing load estimates relative to the existing NAVAIR Processing hardware.
