How Can Millimeter-Wave Radar Enhance Safety in Underground Spaces?
Millimeter-wave radar (mmWave radar) is rapidly emerging as a critical technology for tunnel and underground safety. Subways, underground parking lots, and mines often face challenges such as poor lighting, dense dust, and complex layouts. Traditional cameras and optical sensors struggle to provide reliable monitoring under these conditions.
Millimeter-wave radar combines strong penetration, high-resolution detection, and precise distance measurement, enabling real-time tracking of personnel, vehicles, and environmental conditions. By providing actionable data, radar helps facility operators maintain safety, optimize workflows, and reduce accident risks.
Can Millimeter-Wave Radar Detect Personnel and Vehicles in Real Time?
Radar systems can accurately detect moving objects within underground spaces, allowing continuous monitoring of personnel and vehicles.
-
In subway stations, mmWave radar tracks crowd distribution and unauthorized access to restricted areas, reducing the risk of accidents and improving operational safety.
-
In underground parking facilities, radar monitors vehicle speed, position, and trajectory to prevent collisions and congestion, supporting intelligent parking guidance.
-
In mines, radar tracks miners’ positions in real time, even under poor lighting and heavy dust, enhancing workflow and ensuring personnel safety.
