Real-Time Detection of Small Unmanned Aerial Vehicles Using A Bio Inspired Mems Sensor

Abstract

Ormia Ochracea-inspired microelectromechanical systems (MEMS) sensors can be arranged in a configuration that detects the direction of arrival (DoA) of incident sound. Previous research results indicate that unambiguous DoA can be determined over 360 degrees in azimuth. To this date, analog readouts have been conducted using laboratory instrumentation. The objective of this study was to develop, build and test a circuit configuration that includes housing and power for the MEMS sensor, and the design of a graphical user interface (GUI) to read the DoA from an array of sensors and triangulate the position of a multi-rotor small UAV using GPS position data. Test fields were performed using a configuration of two nodes to detect a small rotor UAV. The operation scenario was displayed on a map. This new configuration can detect sound from any detectable source and provide the coordinates of the source of the sound.
