Electronic warfare has been an important tactical means of the Russian army since the outbreak of the Ukrainian crisis. Especially in the context of the widespread use of GPS and drone technology on the modern battlefield, jammers have become a key weapon for Russia to weaken Ukraine's precision strike capabilities. GPS jammer Russia's Pole-21 jamming system can effectively interfere with GPS signals and block the navigation functions of drones, cruise missiles and precision-guided bombs by emitting strong radio signals. Wifi jammer Its range can reach 15 miles and is considered an important barrier to protect Russia's strategic facilities.

　　However, jammers are not omnipotent. The Pole-21 system not only interferes with the enemy's communication and navigation signals, but also causes trouble for the radio communications of its own troops. cell phone jammer This makes the operation of Pole-21 very cautious, and jammers can only be fully used if it is ensured that it will not interfere with its own troops.signal jammer The U.S. Army pointed out in a report that all radio frequency users within the interference range of the Pole-21 system may be affected, which means that jammers can sometimes become a "double-edged sword" on the battlefield.

　　How does Ukraine deal with Russia's electronic warfare?

　　Faced with Russia's electronic warfare, Ukraine did not sit idly by. According to statistics, since the outbreak of the war, the Ukrainian army has destroyed at least 40 Russian jamming systems, each of which may be worth tens of millions of dollars. Ukraine's anti-jamming operations show that although Russia has an advantage in electronic warfare, Ukraine is gradually weakening this advantage through precision strikes and intelligence gathering.
