Acoustic Stealth and Counter-Detection: Signal Shaping and Masking in SDS Platforms Fundamentals Training by Tonex
Quiet power defines survivability. This program builds a rigorous foundation in acoustic stealth for Subsea/Seabed/Secure Distributed Sensor (SDS) platforms, emphasizing controllable signatures, adaptive masking, and resilient detection avoidance. Participants translate physics-based models into design and operational choices that reduce intercept probability without sacrificing mission performance. Cybersecurity intersects directly with acoustic stealth because compromised signal chains, DSP firmware, or edge-AI classifiers can betray platform intent and timing. Secure signal pipelines, authenticated updates, and tamper-aware telemetry prevent acoustic deception and data poisoning. The result is integrated stealth across hydro-acoustics, controls, and cyber assurance for contested maritime environments.
