Cuirass-M

narrow-base multilateration system for UAV 3D positioning and recognition

Designation

Detection, identification, recognition and 3D positioning of unmanned aerial vehicles (UAVs) by their data transmission link signals.

Tasks resolved

— detection of UAV data transmission link signals and their registration;

— identification of UAV type and instance;

— automatic positioning of UAVs in 3D space through multilateration;

— UAV tracking and trajectory displaying on an e-map and 3D terrain model;

— alarming the operator on UAV detection;

— automatic functional check of the system equipment operation.

System composition

— control station (operator’s workstation and signal processing unit);

— 4 local signal receiving points;

— a set of cables and optical patch

Advantages

— high authenticity of detection and recognition of UAVs based on comprehensive analysis of signals, coordinate and trajectory information;

— high accuracy of determining the UAV coordinates and plotting trajectories in 3D space;

— building a 3D model of the protected facility, optimization of the system setup and topology in accordance with the facility configuration;

— possibility of integration with radar, optical, thermal imaging assets as well as counter-UAV electronic warfare assets.
