The rampant flying of unauthorized drones leads to the emergence of antidrone market which is now on the right track. The jamming technology aiming to interfere with and counter unauthorized flying drones is necessary, when drones are used maliciously in civilian and military fields. Professionals in the anti-drone industry said that the current anti-drone technology is still in the exploratory stage. The radio hijacking technology is difficult to achieve due to the encryption of radio signals by various drone manufacturers, and the hacking technology is not easy to commercialize as it has a high threshold. Therefore, the currently anti-drone technology is mainly about jamming and blocking.All Rights Reserved
