The first use of electronic countermeasure jamming technology dates back to World War II: radar-controlled artillery shot down many Allied aircraft. These systems use radar signals to block and track air targets and direct air defense firepower. When conducting key joint operations, the Resistance placed signal blockers near these weapons. Especially gun-type drone jammers, the designers of guns are too arrogant to consider the possibility of interference, so they have never adopted a "manual override" switch.
UAV jammers are used in various countries, but due to their high cost, they are mainly used by some government or military personnel. The international security organization Europe Security and Cooperation Organization, which has been monitoring the conflict in Ukraine, also reports that it is used for surveillance Frontline drones were intercepted several times. On the Syrian battlefield, four U.S. officials told NBC News that Syria was retaliating against attacks by the rebels in the eastern Guta area, so it began to block some small drone GPS systems through drone jamming devices.
Jamming devices are more effective than conventional weapons. Here, when a signal is transmitted in a specific frequency band, a higher interference signal than the initial signal blocks communication. It turns out that the Russian advanced jamming team developed by the Russian army has proven effective even for certain encrypted signals and anti-jammer devices.
