Passive full-band RF detector

RF drone detection that hears the aircraft before anything sees it

A passive RF drone detection system that sweeps 300 MHz to 6 GHz, recognises over three hundred drone models by protocol, and puts a bearing on both the aircraft and its remote control. Nothing is transmitted, so nothing gives the site away.

What the RF sensor does

01 / Capability
FULL-BAND
Over 300 models identified

Consumer drones, WiFi toy drones, DIY FPV builds and analogue or digital video links — recognised by protocol signature, not just by energy.

POSITIONING
TDOA + AOA + protocol

A single station measures direction; protocol analysis resolves the position of the drone and its controller; several stations give TDOA fixes.

ALL-WEATHER
24/7 in any weather

Unaffected by darkness, haze, rain or lightning. Suitable for complex electromagnetic environments and continuous unattended watch.

FRONT-END PROCESSING
Low false and missed alarms

Reception, RF and signal processing all happen at the sensor head, with micro-signal recognition to cut false and missed alarms.

02 / Specification

One station, or a network of them

Any number of RF drone detection stations can be added to cover a larger area; stations share tracks and cooperate on TDOA positioning.

First warning, then the picture

RF gives the earliest cue and the operator's identification of the model. Radar tracks it, optics confirm it.

01
RF radar

Passive detection and model identification across the full band. You are here.

02
Doppler radar Ga-5000

360° tracking of low, slow and small targets, including drones flying without a link.
