China Claims New ‘Storm Eye’ Concept Creates Electromagnetic ‘Calm Zone’.

With this “New Innovation” Chinese forces would be self-sustainable in protecting their own troops, and allies from signal jamming disruptions while disabling enemy communication.

Chinese scientists have developed an advanced electronic warfare technique that can create a zone of electromagnetic calm, similar to the eye of a storm at the heart of an intense signal jamming environment. This ground breaking innovation could allow Chinese military forces to disable enemy communications and navigation systems while protecting their own troops and allied networks from collateral disruption.

The technology, although at an early stage with feasibility verified in computer simulations, relies on coordinated unstaffed aerial platforms that emit precisely-tuned radio frequency (RF) interference.

By adjusting the waveform, amplitude, phase and relative timing of their signals, these drones can generate a targeted null at friendly positions where jamming signals are cancelled out.

“Under the simulation condition of a 20 dB interference-to-signal ratio, electromagnetic interference at the target legitimate user can be reduced to zero”, wrote the team led by Yang Jian, a professor at the Beijing Institute of Technology. This dual capability, jamming adversaries while safeguarding allies, marks a significant evolution from traditional electronic warfare, which often relies on brute force. This usually comes in the form of omnidirectional jamming that disrupts everything within range, friend or foe, according to Yang and his collaborators from the National Key Laboratory of Wireless Communications in Chengdu, Sichuan. The concept hinges on two drones acting in tandem.

• One serves as the primary jammer, targeting enemy radar or communications;

• The second acts as a “coordinated nullifier”, emitting a counter-signal engineered to destructively interfere with the jamming wave at a specific location, typically where friendly forces are operating. When the two signals converge, they cancel each other out at that precise point, creating the null.

But the success of the technique depends on nanosecond level synchronisation between the two platforms. Even tiny clock errors measured in picoseconds can misalign the signals, weakening the null or shifting it off-target. To address this, they have incorporated adaptive algorithms that use feedback from the null zone to continuously monitor residual interference and adjust the drone signals in real time. Using gradient descent techniques, the system fine-tunes the phase and amplitude to deepen the null even as conditions change.

Their simulations show that the strategy boosts the effective data rate for friendly users by an average of 3.2 bps/Hz (bits per second per hertz) compared to conventional jamming methods. Even under non-optimised conditions, the improvement is 1.5 bps/Hz. It is significant, as military bandwidth can go from tens of megahertz to several gigahertz.

The study also explores multi-node coordination, linking three or more drones into a resilient mesh network. If one platform drifts out of sync, others compensate, ensuring the integrity of the electromagnetic umbrella. This level of sophistication aligns with recent developments showcased at last year’s Zhuhai air show, where China displayed new electronic warfare pods for long-endurance, medium-altitude drones, platforms ideal for sustained electronic dominance over contested regions like the Taiwan Strait.

These pods integrate threat detection, jamming, decoy deployment and laser-based countermeasures against infrared-guided missiles. With power outputs now reaching 15 kilowatts comparable to advanced fighter jets, these systems can operate continuously, turning previously vulnerable drones into survivable frontline electronic warfare assets.

Western analysts note that Russia’s war in Ukraine has exposed the dangers of untargeted jamming. Over the Baltics, Russian electronic warfare has repeatedly disrupted civilian GPS signals, affecting hundreds of commercial flights daily. While Moscow claims this is collateral damage from efforts to counter Ukrainian drones, some officials accuse it of waging a “hybrid war” against NATO nations.

Chinese scientists has achieved ground breaking advances in high-precision time synchronisation that could be crucial for next-generation electronic warfare and quantum communication.

In a landmark experiment conducted across a 113 km (70 mile) baseline in Xinjiang a few years ago, a team from the University of Science and Technology of China synchronised two optical atomic clocks using laser pulses transmitted through free space. This achieved a synchronisation precision of less than one second in 80 billion years, rivalling the stability of the clocks themselves.

Precise timing technology can also lead to powerful directed energy weapons that can converge multiple beams into one.
