Exploring the state of the art in radio frequency inhibitors devices

Abstract

Different explorations have been carried out at the Research Center (CEINV) of the School of Military Communications (ESCOM) located in the city of Facatativá (Cundinamarca), in order to develop the design of an inhibitor or 'jammer' of drones, by means of a modulating wave with a triangular signal shape added to a white noise in order to have the characteristics of swept jamming, because, in the standard 802.11 is sensitive to this type of interference, which is used for drone control.

It should be noted that there are different jamming strategies depending on the need and the conditions of the environment, where those that can be defined as wideband noise jamming, partial band noise jamming and narrowband noise jamming will be used, from which four types of jammers are derived based on the aforementioned strategies (Instituto Politécnico Nacional de México, 2001). Therefore, the most optimal one will be chosen to fulfill the objective of being able to interrupt the control signal of a drone.
