Modular Sonar Identification System (MoSIS)

We propose to develop a Modular Sonar Identification System (MoSIS) (Figure 1). MoSIS will be designed to integrate with the PMS-485 Shallow Water Surveillance System (SWSS). MoSIS will be designed to provide low Size, Weight, and Power (SWaP) capabilities for advanced sonar signal processing. MoSIS will also offer easy development for integration of new algorithms, a modular approach that allows for in-situ upgrades for software capabilities (via Iridium Radio level bandwidth), and compatibility with existing legacy sonar processing algorithms. MoSIS will represent a significant increase in processing capabilities, allowing integration of ADS planar arrays (vs. current linear arrays), reduction of prototype cost, and reduction of power consumption to improve system persistence. MoSIS offers the opportunity to significantly increase processing speed of sonar algorithms such as adaptive beam-forming and target classification, while maintaining a low SWaP profile that will increase system persistence in underwater environments.
