Lilit system detects and classifies battlefield radio signals

The portable REP complex can work alone or in a network to identify emitters across a wide frequency range

Lilit is a portable radio-electronic protection and signal-intelligence system designed to make the battlefield radio environment more visible. Instead of focusing only on jamming, the system is built to detect, direction-find, classify and analyze radio-frequency signals across a broad spectrum.

That matters because modern combat is saturated with emitters. Drone-control links, analog video streams, radio stations, mobile phones, Wi-Fi access points and navigation signals can all reveal activity. The practical value of Lilit is the ability to separate these signals, recognize them and help a unit understand where a relevant source may be located.

Standalone or networked operation

The system can operate as a standalone device for REP units or as part of a network of two or more integrated complexes. In networked mode, several positions can compare detections and improve the accuracy of emitter-source identification. For units working against drones or radio-controlled threats, this can shorten the time between detection and response.

Lilit covers an operating frequency range from 6 MHz to 6 GHz. The detected signal spectrum includes GPS, mobile phones, radio stations, Wi-Fi access points, UAV control signals and analog video streams. This range makes the system relevant not only for counter-UAV work, but also for broader monitoring of tactical communications and electronic activity.

Filtering and signal fingerprints

A key feature is the built-in adaptive preselector. It helps filter jamming and other interference before analysis, which is important in a dense electronic warfare environment where useful signals can be weak, distorted or hidden among stronger emissions.

The system also uses an integrated database of spectral fingerprints. Such a database helps compare detected emissions with known signal patterns and classify them faster. For a field team, this reduces uncertainty: the operator is not only seeing activity on the spectrum, but can connect it to a probable type of source.

The stated detection range is up to 30 kilometers. Combined with networking, classification and direction finding, Lilit becomes more than a portable spectrum monitor. It is a tool for building a radio-frequency picture of the battlefield and turning invisible emissions into actionable information.
