Exploring the Power of 4D Millimeter-Wave Radar in Industrial and Automotive Systems

What Is 4D Millimeter-Wave Radar?

4D millimeter-wave radar represents the next generation of radar sensing. Unlike traditional radars that track position and speed (2D or 3D),4D radars simultaneously detect distance, angle (azimuth and elevation), and velocity, offering real-time three-dimensional mapping with motion tracking.

Linpowave’s 4D radar modules usemillimeter-wave frequencies (76–81 GHz), providing ultra-fine resolution and high-precision object differentiation. With this technology, systems can distinguish between pedestrians, vehicles, and stationary objects—even in poor visibility environments.

Industrial and Traffic Applications: Beyond Automotive Use

While 4D radar is often associated with advanced driver-assistance systems (ADAS), Linpowave extends its capabilities intoindustrial automationandsmart traffic:

• Industrial Robotics: Accurate spatial awareness in autonomous mobile robots (AMRs)

• Safety Zones: Non-intrusive detection of presence in restricted zones, even behind obstacles

• Traffic Monitoring: Multi-lane, high-speed object tracking across intersections, bridges, and tunnels

Compared to camera or LIDAR systems, Linpowave’s radar providesall-weather, low-maintenance sensingat a significantly lower cost with high scalability.

Key Advantages of Linpowave’s 4D Radar Technology

• High Angular Resolution: Enables detection of multiple objects in tight proximity

• Clutter Suppression: Reduces false positives from reflections, ideal for complex factory floors or roadside scenes

• Vertical Elevation Sensing: Tracks object height, crucial for drone/robot detection or tunnel clearance monitoring

• Wide Field of View: Captures objects approaching from multiple directions

• Low Latency & Fast Refresh: Real-time feedback for dynamic environments like autonomous vehicles or robotic arms

These features are embedded in Linpowave’s radar solutions through custom firmware and signal processing algorithms, available as modules or system-level integration kits.

Case Example: Enhancing Traffic Control with 4D Radar

On Linpowave’sTraffic Series solution, 4D radar plays a vital role inadaptive traffic management:

• Counts and classifies vehicles

• Measures speed and arrival direction

• Enables adaptive signal timing for each direction

• Functions under rain, fog, or poor lighting where cameras fail

This results in reduced congestion, increased safety, and more intelligent road infrastructure—all powered by compact, embedded radar units.

Future-Proofing Automotive Systems

4D radar is critical to the future ofautonomous driving and ADAS. Unlike cameras that rely on light and LIDAR that may struggle in dust or rain, Linpowave radar modules ensure:

• Long-range tracking up to 200m

• Instant target classification

• Performance unaffected by weather or lighting

• Compatibility with sensor fusion (camera + radar)

Whether it's blind spot monitoring, cross-traffic alert, or autonomous navigation, 4D radar provides the stable perception backbone vehicles need to operate safely in all conditions.
