To overcome the limitations of existing active-passive sonobuoys—such as disposable batteries, fixed mission parameters, and restricted control capabilities following deployment—this project aims to develop an intelligent sonobuoy architecture that can be remotely programmed during missions.

The scope of this study will combine underwater acoustics, hydrophone-based signal detection, Analog Front-End (AFE) design, RF-based communication, embedded system architectures, and digital signal processing techniques. Ultimately, a software-defined, modular, and highly adaptable system will be established, ensuring extended operational endurance through low power consumption.

Criteria and Expectations

• A strong interest in analog and digital circuit design, low-noise Analog Front-End (AFE) development, and multi-layer PCB layout engineering.
• Knowledge of hardware design in compliance with EMI/EMC principles, alongside low-power management techniques.
• The capability to conceptualize microcontroller-based systems, RTOS-based architectures, RF communication systems, and underwater acoustic data transmission frameworks.
• The ability to perform real-time data analysis utilizing digital signal processing algorithms, such as FFT, filtering, spectral analysis, and noise suppression.
• Demonstrated proficiency in fundamental electronics and simulation processes, with a strong aptitude for integration methodologies within defense and submarine systems.
