Kozak A. The operation of acoustic systems under conditions of noise loads

In connection with the growing requirements for aerial surveillance and reconnaissance systems, as well as the need to improve the existing fleet of UAVs in terms of reducing radar and acoustic visibility, the task of developing an acoustic noise direction finding system for small aircraft based on direction finding methods that have been successfully used was formulated and solved in underwater acoustics. Noise direction finding methods have been refined in terms of compliance with system operating conditions: acoustic antenna (AA) – detection device (up to 5 types of detection devices) – direction finding and indication device. The purpose of the work is to create an acoustic system of airborne noise direction finding, which implements the principles of detecting noise-like signals using spectral and correlation methods.
