Custom multi-static + Ubiquitous

Plextek · United Kingdom

UK engineering house. Proof-of-concept multi-static passive radar with Cranfield University and L3Harris — demonstrated detection and tracking of small UAVs using terrestrial broadcast towers. Receiver nodes use track-before-detect to reduce false alarms and improve low-SNR detection. Bespoke fusion engine combines detections across the network for 3D tracking. Plextek also offers Ubiquitous Radar (active PESA) with continuous surveillance via fixed beams.
