Multistatic ISAC
Distributed Cooperative Radar Mesh
A mesh of multiple distributed base stations and user devices cooperatively illuminating and capturing radar reflections to generate photorealistic 3D holograms of environments.
Technical Explanation
Multistatic ISAC scales sensing to an entire cellular network. Multiple base stations, connected vehicles, and user phones illuminate an environment from dozens of diverse angles simultaneously. Advanced signal processors fuse the multi-static echoes, resolving occlusions, calculating 3D velocity vectors (not just 1D radial velocity), and reconstructing high-resolution 3D environmental digital twins in real time.
Key Functions
- Cooperative multi-node spatial illumination and echo fusion across urban grids
- Resolving target occlusions and blind spots by viewing scenes from multiple perspectives
- True 3D velocity vector computation (Cartesian x, y, z) rather than 1D radial velocity
- Generating dense, photorealistic 3D environmental point clouds for smart cities
- Immunity against single-sensor failures or localized physical blockages
