Potential adversaries in the field of drone jamming – China and Russia
With the drone industry taking off, some groups and groups have started to use drones for malicious purposes around the world. Many companies are watching this trend and trying to enter the counter-drone industry. They have launched a variety of drone guns, anti-UAS shotgun shells, attack birds, net cannons, lasers, missiles, GPS signal jammers, bluetooth blocker, radio scammers, and more.
The drone does not appear to be hit by projectiles or lasers during its descent (although such evidence would certainly change this analysis). In addition to physical projectiles, there are three known non-kinetic methods to stop drones: radio frequency (RF) jamming, global navigation satellite system (GNSS) jamming, and fraud. Communication between the drone and its operator is cut off due to radio frequency interference, often causing the drone to descend or head for home. With GNSS, the drone’s link to the sat nav is lost, and the drone typically turns around, lands, or heads to home. After scamming, the attacker provides the drone with new information to control its flight.
In particular, Crimea’s move was successful and bloodless, also because all Ukrainian military communications were disrupted. Not that they would love to receive them … many just joined the Russian Army and Navy with great enthusiasm.
It doesn’t “enclose” anything. It first caused a major alarm in radar range until software or a human pressed the “seek for jamming” mode button, and the weapon system locked onto the signal blocker. In true peace, the jammers will be eliminated within seconds. Not wanting to make it a cold war, the American ship made the jammer think it was escaping it. Not at all.
China continues to develop capabilities aimed at limiting or preventing adversaries from using space-based assets in times of crisis or conflict, including the development of directed energy weapons and satellite jammers.
The result is that many potential adversaries, such as China and Russia, have developed advanced digital radio frequency memory (DRFM) jammers. These jammers can ineffectively memorize incoming radar signals and repeat them back to the sender, severely hampering the functionality of friendly radars.
