Russian kamikaze drones "Geran-2" have begun to be equipped with a full-fledged passive module for receiving and processing radio signals, the same devices used by Kh-31P missiles. This was reported by the Telegram channel "Military Chronicle".
Analysts, citing foreign researchers, noted that the analog signal from two antennas is fed to a high-speed two-channel converter AD9684, after which it is sent to the digital path of the processor for further processing.
The configuration is atypical for simple telemetry or a navigation receiver. "Geran" collects and processes radio signals, comparing them, possibly, with a database or a pre-loaded target profile, which was previously characteristic only of cruise missiles.
The scheme allows comparing signal parameters, which makes it possible to determine the direction to the source of radiation. In practice, this opens the way for passive homing on active radio-emitting targets. That is, like the Kh-31P missiles.
The authors of the channel stated that "Gerani" have gained the ability to detect targets by their "electromagnetic signature." The primary targets are radars of air defense systems, electronic warfare stations, and any powerful sources of radio frequency radiation.
As a reminder, Kh-31P missiles are used by Su-35 fighters. The missile is guided to the source of radio emission, and if the radar is turned off, it is able to continue flying to the target thanks to the inertial control system.
