High‑Precision 4D Imaging Technology

Technical Principle

4D imaging radar adds elevation to range, speed, and azimuth – delivering a complete 3D view of traffic. Its MIMO array generates tens of thousands of high‑density point clouds per second, capturing distance, velocity, angle, and height. Advanced algorithms turn this data into stable 4D trajectories (position, speed, heading, height) – even in curves or dense, overlapping traffic. Unaffected by darkness, rain, or fog, it provides continuous, reliable sensing for expressways and highways – where every meter and every millisecond matters. It empowers traffic management with real‑time, actionable insights – reducing incident response time and improving overall road safety. By enabling proactive control and dynamic lane management, it helps keep traffic flowing smoothly, even during peak hours.

Key Features

1. High‑resolution 4D imaging – MIMO array and FMCW modulation deliver dense point clouds, clearly reconstructing target shape, size, and motion – turning raw data into vivid images.

2. High‑density point cloud output – Tens of thousands of points per second, capturing every detail of target contour and attitude, providing the richest perception data for decision‑making.

3. High‑stability continuous tracking – Fusing range, speed, azimuth, and height to output smooth, jitter‑free, high‑resolution trajectories over long distances.

4. High‑precision all‑round sensing – Decimeter‑level range accuracy and 0.1m/s speed precision, with accurate elevation measurement – ensuring reliable positioning in every dimension.

5. High‑reliability in all conditions – Unaffected by rain, snow, fog, or darkness; effectively overcomes curves and parallel‑vehicle blind spots that challenge traditional 3D radar.
