The photo evidence released by the Ukrainian government army shows that the Russian military has deployed advanced R-330ZH "resident" automatic communication countermeasure system to the Ukrainian battlefield. This Russian electronic warfare system can intercept, analyze, locate, and interfere with signals from international maritime communication satellites, mobile networks, and GPS. But this setElectronicsThe combat system was destroyed by the Ukrainian government army before it was activated.

The R-330ZH electronic warfare system, also known as the Zhitel system, is designed and manufactured by the Russian company Protek specifically to interfere with enemy communicationsElectronicsThe composition of the combat equipment is very simple, mainly consisting of a jamming machine and four phased array antennas. The antennas are installed on a scalable mast, which is conducive to increasing the coverage of interference to ground communication equipment. Although the composition is simple, the monitoring and interference frequency bands of this system are very wide. In monitoring mode, R-330ZH can cover the frequency range of 100MHz to 2000MHz, while in interference mode, it mainly interferes with the special frequency points of 1227.6MHz and 1575.42MHz, as well as the frequency range of 1500 to 1900MHz. Why are these two frequency points special? Because they happen to be the center frequencies of the US GPS military and civilian code carrier frequency bands.

The entire system consists of two parts: a 6 × 6 truck and a trailer. Trucks are usually Ural-43203/KAMAZ-43114 chassis, carrying reconnaissance and jamming shelters, and a top direction finding dedicated antenna array that can be raised. The full cabin mainly completes the detection, analysis and processing of surrounding signals, measurement of key parameters, and generation of interference signals. The trailer shelter behind ispower stationResponsible for providing power to the entire system, the four corners of the power station cabin are equipped with four masts, all of which can be raised and lowered. If necessary, four active electric scanning antennas can be raised to cover a range of 20-30 kilometers around (azimuth search range: -90 to 120 ° elevation search range: -15 to+20 °). The electric scanning antennas not only include the main transmitting and receiving antennas, but also the RF front-end of the transmitting and receiving antennas. During the operation of the entire system, there are five receiving antennas (one direction finding antenna array for the front vehicle and four antennas for the rear vehicle), while the transmitting antennas are only four for the rear vehicle. The maximum marching speed of the entire system is 85 kilometers per hour, and the deployment time does not exceed 40 minutes.

At the same time, the Ukrainian military discovered a Russian 1RL257 "Krasukha-4" multifunctional jamming station in Makariv village, Kiev Oblast. Krasukha-4 is a mobile active jamming system that specializes in jamming multifunctional radars, drones, ground radars, and reconnaissance satellites of US and NATO early warning aircraft, reconnaissance aircraft, and multi-purpose aircraftradarThe detection. It is said that this Russian military "Krasukha-4" can interfere with radar within a range of 300 kilometers. At present, it is possible that the most powerful and mysterious electronic warfare weapon thrown by the Russian military has appeared in areas such as Syria and Donbass. The specific information about it is not known to the outside world, only that a complete "Krasukha-4" electronic warfare system consists of two parts, including a command module and an electronic warfare module, which are carried by two KAMAZ-6350 off-road trucks. Its origin can be traced back to the late 1990s, but it remains one of the most powerful mobile electronic warfare systems in the Russian military, and mass production only began in the early 2010s, with equipment for the Russian military only beginning around 2014.

Russian officials have claimed in the past that Krasukha-4 can detect and interfere with various types ofradarThis includes surveillance radar, airborne radar imaging sensors, as well as active radar seekers and altimeters in missiles. According to the manufacturer Concern Radio Electronic Technologies (whose Russian acronym is KRET), its maximum range for ground and airborne targets is between 150 and 300 kilometers, or approximately 93 to 186 miles in any direction, depending on various environmental factors. It is currently unclear whether this reflects the range within which radar can be detected, engaged in combat, or both. There are reports that the interference system of Krasukha-4 can emit a sufficiently powerful RF energy beam, causing physical damage to sensitive electronic systems on certain targets.

From the on-site situation, it appears that the command module of this' Krasukha-4 'has been abandoned, and the Russian military has only driven the off-road vehicle. Perhaps the command module has been damaged, but it still has enormous research value for countries such as the United States. In 2015, the Russian military claimed that the Krasuha-4 had rendered several American made Tomahawk cruise missiles targeting Syria ineffective and caused some American fighter jets to malfunctionNavigationmalfunction. If the news released by the Ukrainian military is true, then this could be a significant loss for the Russian military so far. The loss of any Krasukha-4 electronic warfare system is not only a serious loss of equipment, but also a serious mistake in the Russian military's combat command. The ability to abandon this cutting-edge electronic warfare equipment without undergoing explosive treatment or even setting it on fire demonstrates the hasty withdrawal of the Russian military. The discovery of many other complete Russian military equipment, including self-propelled artillery, in the northern region of Kiev also confirms this. It is unbelievable that this supportive electronic warfare equipment has been captured by the Ukrainian army. If it were not for the fake news from the Ukrainian army, the morale of some Russian front-line troops may be at a worrying level.
