VAAS (Visual Acoustic Analysis Software) is an advanced solution for underwater acoustic signal processing, passive surveillance, and post-processing analysis. Designed for both live operations and mission replay, VAAS transforms raw underwater sound into actionable intelligence.
VAAS provides accurate detection, tracking, and classification of acoustic sources in cluttered and dynamic maritime environments. Its modular architecture integrates seamlessly into new command installations or existing fleet infrastructure, supporting flexible deployment across platforms. It mirrors naval workflows with intuitive visualization tools, automated replay modes, and training modules.
