Open Sonar Acquisition & Modular Signal Processing Hardware Training by Tonex
Open sonar hardware connects physical sensor measurements to mission applications through tightly coordinated acquisition, timing, digitization, transport, and signal processing functions. This course studies modular sonar acquisition chains for submarines, with attention to low-noise front ends, converter performance, synchronization, processing throughput, and well-defined digital interfaces. Participants evaluate processing architectures without assuming that a generic computing standard resolves sensor-specific acoustic or timing requirements. The curriculum emphasizes engineering tradeoffs, documented performance boundaries, interoperability, and verification evidence for maintainable, upgradeable underwater sensing capabilities.
Cybersecurity requirements apply to calibration records, sensor interfaces, acquisition firmware, and derived data. Protecting integrity and access to these elements improves cybersecurity and supports trustworthy sonar processing results.
The practical training approach includes exercises, real-world case studies, and examples of processes and documentation used in submarine open hardware engineering projects, including acquisition interface specifications, timing diagrams, signal fidelity budgets, calibration records, and modular processing test reports.
