This truck-mounted system is designed to target enemy airborne data links and is equipped with a log-periodic dipole antenna (LPDA) for ultra-wide bandwidth (UWB) applications, according to information shared on Twitter by clanon.

The open-day event, held in Changchun, Northeast China's Jilin Province, includes various activities such as air dynamic performances, ground static displays, exhibition halls, and more. Coinciding with the 70th anniversary of the end of the Korean War (1950-53), the event aims to showcase China's efforts in strengthening its PLA Air Force, seeking to achieve world-class status in the military domain.

Lieutenant-Colonel Hou Jian, from the Equipment Department of the PLA Air Force, stated that a total of 45 aircraft of 13 types, along with 96 different types of equipment across 137 ground displays, would be featured in the event. In addition to the new RCT195B data chain tracking and disturbing station, other exhibits included the Z-20KA helicopter, the 120mm self-propelled howitzer, and legacy aircraft that reflected the PLA Air Force's transition from importing foreign equipment to independent research and development. Furthermore, the event aims to demonstrate China's progress in building a robust air force capable of fulfilling its defense and security objectives.

The RCT195B data chain tracking and jamming station displayed during the event plays a significant role in electronic warfare. Radio jamming, as exemplified by this system, involves intentional interference, blocking, or disruption of wireless communications. It can be executed through obvious means, such as introducing noise or interfering signals that disrupt normal transmission, or through more sophisticated methods like subtle jamming, where interference is harder to detect.

As technology advances, the RCT195B can effectively disrupt enemy airborne data links and interfere with complex digital signals using modulation techniques like QPSK. This disruption can hinder the communication process and prevent legitimate connections from being established.

While radio jamming is a strategy of strategic military significance, it is essential to consider that intentional radio jamming is deemed illegal in many countries due to its potential to disrupt critical communications, emergency services, and legitimate radio transmissions.
