6G Sensing Resolution Metric
Spatial and Velocity Radar Resolution Capabilities in IMT-2030
Performance benchmark defining spatial range resolution (<1 cm) and velocity precision (<0.1 m/s) for 6G network radar sensing.
Technical Explanation
In Integrated Sensing and Communication (ISAC), the 6G network acts as a distributed radar. The IMT-2030 sensing capability specifies spatial range resolution down to centimeters (governed by the bandwidth c/(2B)) and Doppler velocity accuracy down to fractions of a meter per second. This enables 6G networks to map indoor rooms in 3D, monitor city traffic flows, detect drone intrusions, and recognize human falls without requiring radar guns or optical cameras.
Key Functions
- Attains spatial range resolution <1 cm using multi-gigahertz sub-THz bandwidths
- Measures target velocity with precision <0.1 m/s via high carrier frequencies
- Creates real-time 3D point-cloud environmental maps of urban environments
- Operates in pitch darkness, smoke, fog, and inclement weather
