Model-Based Systems Engineering Design for a Counter-UAS System for Infantry Platoons

Unmanned Aerial Systems (UASs) have become essential for targeting high-value assets due to their low cost and operational versatility, posing significant battlefield challenges. This study addresses the need for a low-cost, lightweight counterUAS (C-UAS) system that integrates seamlessly into infantry platoons. Using a model-based systems engineering (MBSE) approach, stakeholder feedback informed use cases and operational requirements, allowing for the development of the system's logical architecture. The study incorporated prototyping to support the development of the system's physical architecture. The prototype featured a Raspberry Pi and a software-defined radio capable of detecting drones and emitting a jamming signal. Soldiers interfaced with the prototype via the Android Tactical Assault Kit (ATAK), a system already deployed on the battlefield. Power was sourced from the conformal batteries worn by soldiers. The prototyping effort yielded critical insights into technical requirements, which were incorporated into the system's design. The lightweight, compact prototype demonstrates significant potential for field deployment, offering infantry units a costeffective, reliable solution for detecting and countering UAS threats. This study provides a foundation for future C-UAS development, addressing the urgent need for enhanced counterUAS capabilities in modern military operations.
