On May 23, 2024, in the Donetsk region of eastern Ukraine, 42-year-old Ukrainian soldier Mykola demonstrated a seemingly simple but crucial battlefield equipment-a drone signal jammer. This equipment plays a key role on the battlefield and has become an important tool for the Ukrainian army in countering Russian drone attacks. cell phone jammer Here is the background, role and future development direction of this technology.

　　Background

　　The introduction of the drone signal jammer marks a tactical innovation for the Ukrainian army in the face of drone threats. Wifi jammerThe device looks like a large white thermos, but its actual function is extremely important. Mykola mounted the antenna of his device on an armored four-wheel drive vehicle to demonstrate its practical application in war.

　　The jammer weighs only 4 kilograms and has a compact design that can be easily loaded into a backpack. This portability makes it one of the first portable electronic protection devices for Ukrainian infantry. Since the escalation of the conflict between Ukraine and Russia, these jammers have become important equipment on the battlefield, helping the Ukrainian army deal with the threat of drones from Russia.

　　The battlefield role of jammers

　　UAV signal jamming systems have played an important role on the battlefield in Ukraine, especially in defending against Russian FPV drone attacks. FPV drones are small and relatively cheap, equipped with real-time image transmission systems, and can carry explosives for precision strikes. Oleksandr Pavlyuk, commander of the Ukrainian Ground Forces, noted that the number of casualties caused by drones has now exceeded that of any other weapon.

　　To counter this threat, the Ukrainian army has adopted jammers. These jammers cut off the connection between the equipment and its pilot by emitting jamming signals at the same frequency as the drone's control signals. Mykola's device is effective within a range of 30 meters and can cause an enemy FPV drone to completely lose control. Designed by a Ukrainian company and funded by private donations, the jammer has been in use on the battlefield since this winter.

　　Technological confrontation and future prospects

　　In this technological confrontation, both Ukraine and Russia are using jammers. Ukrainian drone pilot "Coyote" said he lost up to 40% of his equipment due to enemy interference. Soldiers from the 28th Brigade stressed that the key to defending against jammers is experience, knowing the operating frequency of the jammer can change the frequency of the drone or try to bypass the jammer.

　　Ukraine started late in electronic warfare systems, but has made significant progress. Mikola pointed out that Russia has more than 30 years of experience in electronic warfare, while Ukraine only started developing related equipment in 2014. Currently, Ukraine is able to jam 60% to 70% of Russian FPV drones, but both sides need to keep innovating and develop new countermeasures every three months.

　　Senior officers said that this is a huge battle and everyone is looking for new ways to counter the frequency and drone threats. In the future, the Ukrainian army will continue to develop and optimize jamming technology to maintain its advantage in this electronic warfare.
