Compact, passive acoustic detection and tracking system for unmanned aerial vehicles (UAVs)

Abstract

Compact detection and tracking system for unmanned aerial vehicles (UAVs), called "Drokil", characterized by: a) A closed, waterproof case with external dimensions of 6x4x2cm, finished in a camouflage color. b) A matte, black front panel integrated into the front of the device, completely concealing the internal components. c) A miniature microphone array integrated into the front panel in the lower left area for acoustic detection of UAV noise. d) A digital compass integrated into the front panel in the upper left area with a visible dial, compass needle and cardinal directions (N, S, W, E). e) An enlarged, green status LED integrated into the front panel for visual indication of system status and warning messages. f) Two waterproof on / off switches integrated into the front panel: an LED power switch (for the status LED) and a device power switch (for the device's main power supply), positioned one above the other at the top right. g) A USB-C charging port integrated into the front panel at the bottom edge. h) An internal 5000 mAh battery for power supply. i) An internal SLC memory chip with associated processor for signal processing, classification of acoustic signatures and bearing of the UAV position in relation to the compass orientation. j) A round magnet embedded in the back of the housing for fastening.

Description

I. Title of the invention Compact, passive acoustic detection and localization system for unmanned aerial vehicles (UAVs). II. Technical Field The invention relates to a system for the acoustic detection and localization of flying objects. III. State of the art Known drone detection systems are often large-scale and not optimized for mobile, individual use. IV. Brief Description of the Drawings The drawings illustrate an embodiment of the invention. They show: Fig. 1 a schematic front view of the acoustic detection system; Fig. 2 A schematic rear view of the acoustic detection system. V. Detailed description of the embodiment The system uses a microphone array (2) to detect sound pressure waves. As in Fig. As can be seen in Figure 1, the housing (1) encloses the electronics. Four microphones (2) are arranged in the corner areas. A tactile main switch (3) is used for commissioning. The direction of the sound source is visualized visually via an LED array (4) and mechanically by a rotating needle (9). A digital compass (5) and a USB-C charging port (6) are integrated for geographical orientation. Fig. Figure 2 shows the fastening options: a magnetic holder (7) or a Velcro holder (8).
