Mathematical model of acoustic noise in multi-drone monitoring systems

A mathematical formalization of the problem of acoustic interference in swarm monitoring systems is presented. Existing approaches are described that solve the problem of suppressing the own noise of a single drone, but do not take into account dynamic acoustic channels and the unsteadiness of the spectrum during maneuvers. A signal model is proposed that takes into account the above factors and serves as a theoretical basis for the development of cooperative noise reduction algorithms. An analysis of the model practical applicability for swarms of several drones is carried out.
