Fractal Antenna Techniques, Inc. has introduced JERECHO™, an acoustic array platform designed for counter-unmanned plane programs (C-UAS) purposes. The system, developed by the corporate’s OWL WORKS™ particular initiatives division, makes use of directed sound know-how for detection, disruption, and associated protection features.
Technical Specs of Acoustic Digital Warfare
JERECHO™ incorporates Fractal’s Acoustic Resonance Mitigation (ARM) framework, initially patented in 2015 and expanded with extra patent-pending know-how. The platform makes use of a sound-based array that focuses on how acoustic waves work together with their medium, enabling operators to direct and management sound propagation. The system employs fractal-based strategies to form acoustic arrays and enhance operational vary.
The platform options wideband sonification capabilities alongside detection and imaging features. Based on the press launch, these components work collectively throughout the broader acoustic digital warfare framework—the corporate’s time period for directed sound know-how purposes in protection contexts.
Demonstrated Capabilities and Testing
Testing has proven measurable results on digital programs. Exactly calibrated ultrasonic indicators have disrupted smartphone navigation programs in managed situations. Small unmanned plane exhibited digicam picture degradation when uncovered to acoustic vibrations throughout testing. FRACTAL CEO Nathan Cohen said these outcomes symbolize reproducible results quite than remoted incidents.
The corporate positions JERECHO™ as a testbed for medium-range counter-drone purposes inside layered protection architectures. The platform addresses detection, disruption, digital spoofing, laser integration, and controlled-flight experimentation capabilities.
Expertise Improvement and Business Context
Fractal’s method to acoustic digital warfare—outlined by the corporate as “novel methods of directing and controlling sound and medium”—represents an evolution of know-how the corporate initially developed. The agency obtained the 2025 Gold Army & Aerospace Innovation Award for acoustic counter-UAS analysis, although the corporate notes that early ARM know-how improvement confronted home skepticism earlier than gaining worldwide consideration.
Cohen said: “Sound waves have lengthy had their place in protection, however we now see a brand new period rising—’acoustic digital warfare’—outlined by novel methods of directing and controlling sound and medium, and thwarting units which can be surprisingly delicate to sound interplay.”
Broader Functions
Past counter-drone features, Fractal describes JERECHO™ as relevant in opposition to a number of gadget classes. The corporate lists potential targets together with drones, robots, smartphones, digital programs, vessels, and unidentified aerial objects. Cohen famous that “sound could be potent in opposition to fashionable machine surrogates reminiscent of drones, robots, smartphones, electronics, vessels, and aerial objects of unknown origin.”
Fractal has developed know-how throughout a number of sectors over three a long time, together with antenna programs, metamaterials, and superior supplies analysis. The corporate positions JERECHO™ because the operational software of beforehand developed acoustic know-how.
