Automation within vehicles—notably in ADAS and emerging autonomous functions—is transforming how safety and control are delivered on the road. In this dynamic environment, millimeter‑wave radar offers contactless, resilient sensing that supports critical tasks like collision warning, adaptive cruise control, and in-cabin occupancy monitoring.
Overcoming limitations of traditional automotive sensors
Conventional systems often rely on cameras or ultrasonic sensors, which struggle in rain, glare, or darkness. Linpowave’s V-Series 4D mmWave radar modules operate in the 76–81 GHz band, delivering reliable distance, velocity, angle, and elevation data over ranges up to 300 m with ±0.23 m accuracy—not disrupted by challenging lighting or weather conditions
These modules support:
-
Adaptive Cruise Control (ACC) for safe car-following
-
Blind Spot Detection (BSD) even in obscured conditions
-
Automatic Emergency Braking (AEB) with millisecond response
Anticipating hazards before they become incidents
Linpowave’s radar can track multiple objects simultaneously, including stationary obstacles or merging vehicles—critical for busy intersections and highways. The 4D radar delivers point-cloud and elevation data that provide improved scene awareness and faster reaction capability in ADAS applications.
Enhancing in-cabin safety while preserving privacy
Millimeter-wave radar also excels inside the vehicle. Without capturing images, it can detect:
-
Unattended children or pets left in seats (Child Presence Detection, CPD)
-
Occupancy and safety-belt usage
Such systems operate through seats and glass, ensuring comfort and privacy while delivering critical safety alerts.
Why millimeter‑wave radar is a superior fit for automotive use
| Advantage | Benefit |
|---|---|
