Introduction
Parking lots are unique traffic environments where vehicles move at low speeds but require high-precision monitoring. Traditional surveillance systems, such as CCTV cameras, often struggle with blind spots, occlusions, and poor lighting conditions. Millimeter-wave (mmWave) radar provides a robust solution, offering accurate distance measurement, real-time tracking, and reliable detection of multiple vehicles, pedestrians, and bicycles in confined areas.
By integrating mmWave radar into parking lots, operators can enhance safety, optimize space utilization, and reduce minor collisions, even under challenging lighting or crowded conditions.
Low-Speed Multi-Target Vehicle Detection
Unlike highways, parking lots present dense and highly dynamic traffic, with vehicles frequently stopping, turning, and reversing. Linpowave mmWave radar addresses these challenges through:
Technical highlights:
-
High-Resolution Detection: Detects vehicles and pedestrians with centimeter-level accuracy, even at speeds below 10 km/h.
-
Multiple Object Tracking (MOT): Radar tracks all moving targets simultaneously, including vehicles, cyclists, and pedestrians, with unique IDs to maintain continuity during occlusions.
-
Close-Range Reflection Management: Parking lots often contain metal structures, barriers, and parked vehicles. Advanced filtering algorithms differentiate moving targets from static reflections.
Engineering considerations:
-
Blind Spot Mitigation: Radar placement and beam shaping ensure coverage of corners, ramps, and narrow lanes.
-
Slow-Moving Object Detection: Low-speed motion produces weak Doppler signals; Linpowave radar adjusts signal processing to reliably detect slow or stopped vehicles.
-
Dynamic Environment Adaptation: Radar adapts to changing vehicle density and pedestrian movement patterns throughout the day.
Safety Management and Collision Prevention
Real-time monitoring enables active safety measures:
-
Proximity Alerts: Radar detects vehicles approaching each other too closely, triggering audible or visual alerts to drivers.
-
Pedestrian Detection: High-priority alerts are generated when pedestrians are in close proximity to moving vehicles.
-
Reversing Assistance: Radar mounted near entrances/exits or on poles can monitor reversing vehicles and prevent collisions with obstacles.
Integration with Parking Management Systems
To maximize utility, radar data can be integrated with smart parking and management platforms:
-
Occupancy Monitoring: Detects empty and occupied spaces in real time, optimizing space utilization.
-
Data Fusion: Combining radar with cameras or access control systems improves overall situational awareness.
-
Analytics: Collects vehicle movement patterns, dwell times, and peak traffic periods, informing operational improvements.
Linpowave Radar Solutions
The LPR-300 series mmWave radar is ideal for parking lot deployment:

Case Study
A large commercial parking facility installed Linpowave radar units at multiple entrances, exits, and tight internal lanes. Within two months:
-
Minor vehicle collisions decreased by 25%
-
Real-time occupancy tracking improved space utilization by 15%
-
Pedestrian safety incidents were reduced due to early warning alerts
This demonstrates mmWave radar’s ability to enhance both safety and operational efficiency in confined, low-speed environments.
Future Outlook
As parking lots evolve into smart, connected facilities, mmWave radar will play a critical role in:
-
Integrating with autonomous parking guidance systems
-
Supporting AI-driven traffic analytics to optimize internal flows
-
Enhancing automated payment and access control with real-time vehicle tracking
Conclusion
