Spread Spectrum Techniques for Sonar Ping Technology

Signal Systems Corporation (SSC) proposes to develop a Spread Spectrum Multistatic Active Covert (SSMAC) sonar system. The proposed research will benefit existing sonar systems and also yield revolutionary system concepts. During Phase I, we will develop algorithms necessary for mitigating undesirable sidelobe behavior of pseudo-random noise spread spectrum waveforms, and highlight the potential of spread spectrum multi-input multi-output sonar technology using in-water simulations. We will conduct an in-air spread spectrum multistatic sonar system demonstration against moving targets. SSC will leverage unique scattering geometries, exploit ocean channel multipath, in-buoy signal processing, multi-input/multi-output sonar techniques and wide band ping technology to pursue a system that is effective, covert and have low marine mammal impact. We will conduct a system level trade study to focus our technology onto a specific ASW mission.
