China’s new electronic warfare tech disrupts enemy systems while protecting friendly signals

Chinese researchers have developed a novel electronic warfare (EW) system that can simultaneously jam enemy communications while preserving friendly signals within a designated “null zone,” akin to the calm “eye” of a storm amid electromagnetic chaos. This technology employs two coordinated drones emitting carefully controlled radio signals—adjusting waveform, amplitude, phase, and timing—to create a point where the jamming waves cancel each other out, allowing allied communications to operate uninterrupted. This approach leverages advanced beamforming and phase cancellation techniques, marking a significant evolution from traditional omnidirectional or directional jamming systems that typically disrupt all signals within range. In simulations, the system demonstrated the ability to nullify interference even when jamming signals were 100 times stronger than the target signals, effectively reducing electromagnetic interference at friendly receivers to zero. Such precise spatial control could enable selective jamming, providing a tactical advantage in contested environments like GPS-denied zones and transforming EW from a blunt instrument into a surgical tool. However, the technology remains at the simulation stage
