Акустичний детектор fpv-дронів

Abstract

The increasing use of FPV (First Person View) drones creates challenges for traditional radar, radio-frequency, and optical detection systems due to their small size and low-altitude flight. This paper considers the principles of acoustic detection of FPV drones based on analysis of the noise generated by propellers and electric motors. A detection approach using a microphone array is proposed. Signal processing includes spectral analysis and time-difference-of-arrival (TDOA) methods for estimating the direction of the sound source and enabling early drone detection
