If the hum of an aerial drone still shocks you, get used to it! The use of drones has spread to all walks of life (entertainment, science, agriculture, news, medicine, military, logistics, etc.) and inevitably to the darker side as well. Meritorious and terrorist groups, once discovering the versatility of drones, now often deploy them as a sort of small air force for surveillance, delivery of legitimate cargo, or full-scale strikes. Rogue drones alone or in groups pose a threat that every law enforcement, security advisor, and defense agency must consider. One of the first countermeasures developed for drones was radio frequency jamming, which targeted the communication channel between the drone and its operator. While this is a relatively low-cost solution, its complexity may limit its usefulness.

Limitations of Interference
Drones are small, a small point in the vast airspace around any purpose, be it people or equipment, whether stationary or mobile. For example, in order to protect an airport from drone threats by jamming its RF communications, identify the frequency of communications and disrupt them at intervals to neutralize the threat. These variables enable targeted Jamming becomes an unreliable solution because it takes some time to lock and analyze the signal, and frequency switching is rare. On the other hand, general offensive measures such as full-scale jamming can lead to many unforeseen situations, since RF signals have very common civilian uses (the most important of which is air traffic control).

Additionally, since RF signals are susceptible to random interference, the drone industry is developing ways to address this vulnerability by maintaining communication channels (necessary for even the most casual routine operations, such as delivering a package to the correct address) ) . While alternative guidance methods, such as GPS positioning, could create a “dark” UAV that could perform its duty independently of any further instruction/communication with the operator.

While radio frequency jamming is undoubtedly the most common method of disrupting and attacking rogue drones, it is clear that as drones become more common and their technologies become more sophisticated, countermeasures against them will need to keep pace. pace.
