Radio jammers: the gap between theory and reality

  The design concept of radio signal jammers is to disrupt the normal operation of drones or even crash them by emitting radio noise to cut off the signal connection between drones and their operators. Wifi jammer This theory seems simple, but it is challenging to implement effectively in complex battlefield environments. In actual combat, the attack paths and patterns of drones are often unpredictable, and the Russian-designed jammers have failed to adapt to these changes.GPS jammer

  An angry Russian blogger exposed the problems of a $2,400 multi-frequency radio jammer on social media. The design errors of the device made it almost impossible to fight against drones. GSM jammerThe blogger emphasized that these jammers gave frontline soldiers an unrealistic sense of security, causing them to die in combat. What's more, the blogger pointed out that this is not the first time that similar jammers have failed on the Ukrainian battlefield. The Russian jammers stolen by Ukrainian troops a few months ago were also proven to be almost useless.

Design flaws: antennas pointing to the sky and overheated equipment

  The blogger analyzed the various design errors of this device in detail. One of the most obvious problems is the improper direction of the antenna. Ideally, the antenna of the jammer should be able to broadcast radio noise in multiple directions to deal with drone threats from all directions. However, the antenna of this jammer is mostly fixed upward, which makes it only work in a specific and narrow airspace. Ukrainian drones, especially low-flying FPV (first-person perspective) drones, often attack from the side, directly bypassing the effective range of the jammer.

  The fixedness of the antenna further exacerbates this problem. For jamming FPV drones, the device designers seem to assume that the drone will appear "precisely" above the jammer, however, the reality on the battlefield is far from this. The attack methods of FPV drones are flexible and varied, and this antenna design obviously fails to take this into account.

The evolution of JDAM-ER smart bombs

- jammerspecialist

Principle and use background of JDAM-ER

  The basic working principle of the JDAM-ER system is to upgrade ordinary free-fall bombs to precision-guided munitions. Wifi jammer It is guided by GPS signals and can adjust its trajectory during flight to achieve precise strikes on targets. The JDAM-ER munition is also equipped with a wing kit that allows it to fly longer distances, with a maximum range of up to 45 miles (about 72 kilometers).drone jammer This allows the Ukrainian Air Force to use Soviet-era fighters such as the Su-24, Su-27 and MiG-29 Fulcrum fighters to carry JDAM-ER to strike key Russian targets. GSM jammer

The impact of electronic warfare interference on JDAM-ER

  While JDAM-ER was initially successful on the Ukrainian battlefield and hit some key Russian targets, this advantage was quickly offset by the Russian military's electronic warfare technology. In just a few weeks, Russia deployed powerful GPS jammers that greatly reduced the JDAM-ER's precision strike capability. According to leaked Pentagon documents, Russian electronic warfare equipment such as the R-330Zh Zhitel transmits jamming signals in the 1.164GHz to 1.575GHz frequency band used by JDAM, preventing these bombs from obtaining sufficient GPS data and thus deviating from their intended targets.

  This interference does not directly cause the JDAM-ER bomb to fail, but it weakens its accuracy, which in turn affects its effectiveness on the battlefield. GPS guidance is the key to the success of the JDAM system, and when Russia deploys electronic warfare jammers, the advantages of JDAM-ER cannot be fully utilized. US analysis believes that unless the jammers are eliminated first, the attack capability of JDAM-ER will be greatly limited.

US Improvement Plan: Home-on-Jam Technology

  In response to Russian interference, the United States quickly took technical improvement measures. On May 3, 2024, the Pentagon announced that it had signed a contract worth more than $23 million with the Science Applications and Research Association (SARA) to purchase a "Home-on GPS Jamming Seeker" and integrate it into the existing JDAM-ER system. This new seeker is designed to enable JDAM-ER to directly target and destroy enemy GPS jammers, thereby removing interference from Ukrainian operations.

  Home-on-Jam technology is not a new concept. As early as 2014, SARA, in cooperation with the US Air Force, began to develop a seeker system that can automatically track jammers. This system has been tested on a variety of weapon platforms, demonstrating its potential for application in complex battlefield environments. In 2020, the U.S. Air Force also tested this technology on the GBU-39/B Small Diameter Bomb (SDB), proving its effectiveness against electronic warfare.

  With the application of Home-on-Jam technology, Ukraine is expected to regain its advantage against Russian electronic warfare. JDAM-ER's improved ability to destroy enemy jammers means that the Ukrainian Air Force will be able to strike key Russian targets more accurately, especially strategic facilities on the front and rear of the battlefield. This improvement will not only improve the battlefield effectiveness of JDAM-ER, but also provide valuable experience for the future development of precision-guided munitions.

  Overall, the failure of JDAM-ER is not a single technical defect, but in modern warfare, the power of electronic warfare has become an important factor in determining the outcome of the battlefield. The United States has shown its determination to meet future electronic warfare challenges by introducing smarter seekers. This battle is not just a confrontation between ammunition and missiles, but also a struggle between technology and electronic warfare systems.
