Arduino-Based sUAS Detection Sensors

State actors have converted small Unmanned Air-craft Systems (sUAS) into weapons capable of carrying explosive payloads, artillery, support for other ground and air forces, logistics, and close battlespace awareness. These devices have become instruments of power, even thwarting Russian advancement into Ukrainian territories. In response to this new strike vector, this paper explores the Arduino ecosystem as a novel approach to creating a distributed sensor network capable of detecting sUAS. We propose an Arduino-based sensor node design that executes a Tiny ML model to detect sUAS through visual, audio, and radar modalities.
