New Ukrainian detector lets infantry watch enemy drone feeds to counter pilot strikes

Kyiv company CODE380 built the D·Vision SDR detector to intercept Russian drone signals into live video, TechRadar reported on Oct. 26.
The system has already completed operational combat trials embedded with frontline Ukrainian combat units and receives continuous software and firmware updates roughly twice a month.
Unlike conventional tactical drone detectors that rely on fixed analog tuner chips to intercept video downlinks, the D·Vision SDR analyzes the radio environment using software-defined radio (SDR) architecture.
The D·Vision SDR scans the electromagnetic spectrum across an ultra-wide range from 500 to 8,700 MHz, actively hunting for distinct radio signatures characteristic of enemy loitering munitions and reconnaissance aircraft.
The primary operational advantage of this SDR methodology is agile adaptability: when Russian drone manufacturers and field operators shift transmission frequencies, the countermeasure requires a simple over-the-air software update rather than a physical redesign of the receiver hardware.
Feedback gathered directly from trench trials informed the hardware's iterative refinements, and the developer currently pushes updated threat signature libraries approximately every two weeks. This update cadence is critical: drone command protocols, hopping frequencies, and telemetry structures in Ukraine shift on an almost weekly basis, rendering static, non-upgradable analog detectors obsolete within weeks.
Converting raw drone signals into decoded video directly counters a growing battlefield threat that intensified throughout 2025 and 2026: Russian loitering munitions are overwhelmingly equipped with thermal and optical cameras guided by human pilots in real time, rather than flying pre-programmed routes. By intercepting and displaying this video feed, Ukrainian infantry gained identical optical situational awareness to that of the hostile drone pilot.
Nonetheless, engineers acknowledge that technological superiority in the electromagnetic spectrum remains temporary. Russian drone units continually modify their radio profiles and tactical deployment doctrines, meaning any tactical detection edge must be vigorously maintained to avoid obsolescence.
Electronic Warfare Race on Non-Standard Frequencies
Ukrainian military communications and electronic warfare specialist Serhii "Flash" Beskrestnov recently issued an urgent warning revealing that Russian forces began fielding Molniya strike and reconnaissance drones on non-standard video transmission frequencies spanning 4.1 to 4.5 GHz (specifically clustering around 4.3 to 4.5 GHz).
Beskrestnov warned that the overwhelming majority of Ukrainian portable drone detectors deployed along the frontline operate on legacy frequency bands (primarily 1.2 GHz, 2.4 GHz, and 5.8 GHz) and are entirely blind or severely degraded when monitoring the 4 GHz spectrum.
"Most detectors do not see these frequencies, or see them poorly. I issue this warning so that misplaced trust in a detector does not cost you your life," he emphasized.
The development of wideband systems like the D·Vision SDR — spanning up to 8.7 GHz — directly addresses these specialized frequency shifts, closing the detection gap against Russian tactical aviation units attempting to bypass frontline electronic surveillance.
The military war may be swinging in our favor, but the information war continues.
Just as an army needs soldiers, so does a free society need its journalists to ensure that people have access to honest, trustworthy voices to understand the world around them.
For the past five years, The New Voice of Ukraine has been working tirelessly to push back against Russian narratives and defend democracy. But we cannot do it alone.
