PASSIVE RF MESH · SYS-01

See every drone. Transmit nothing.

AISAR Detect analyses the electromagnetic spectrum without emitting a single signal. It identifies the control link, the video downlink and the telemetry of a drone, classifies the model, and locates both aircraft and operator. No emissions. No spectrum authorisation. Nothing for anyone to detect.

AISAR Detect passive RF mesh
CAPABILITIES
Passive RF detection

Covers 400 MHz – 6 GHz — every commercial drone band. Identifies controller links, video transmission, telemetry and proprietary protocols including DJI OcuSync and FHSS families. Reception only: invisible to counter-detection, no authorisation required anywhere in the EU.

AI classification

A three-level convolutional network answers three questions in sequence: is it a drone, what class of transmitter, what specific model. 37 drone classes from RF fingerprint alone, including DJI, Autel, FPV and custom-built platforms. Models trained on operational recordings, not laboratory captures.

Mesh geolocation

Three or more nodes correlate time and frequency of arrival to produce meter-class geolocation, with cross-node correlation giving velocity and heading. Coverage scales linearly: five nodes cover 25+ km² with overlapping sectors.

Edge processing

Every node classifies locally on NVIDIA Jetson AGX Orin. No cloud dependency, no backhaul, no latency, no data leaving the site unless you choose. Pipeline: FFT → Spectrum Environment Monitor → CFAR detection → CNN classification.

Spectrum Environment Monitor

The node learns the baseline electromagnetic environment of the specific site, then flags what does not belong — cutting false positives sharply compared with fixed-threshold detection. The baseline adapts as the site changes.

Reflected signal analysis

Bistatic and multistatic geometry using ambient Wi-Fi, GPS, 5G and broadcast signals reflected off aerial objects, extending passive coverage toward targets that transmit nothing.
