Analysis of electromagnetic and acoustic radiation of un- manned aerial vehicles

Authors: Bombizov A. A., Petrov A. B., Loschilov A. G.

Annotation: This article is devoted to the problem of reliable and early detection of hardly noticeable unmanned aerial vehicles carrying out unauthorized access to protected objects. The article deals with a direction that uses only the observation of the intrinsic electromagnetic radiation of the aircraft. In particular, registration and comparison in the frequency domain of intrinsic electromagnetic and acoustic radiation has been performed. The relationship between the spectral characteristics of the signal and the frequency of rotation of the engines is determined.
