Jianhe Bafang FiDAR Fiber‑Optic Radar Vehicle Positioning and Tracking System

FiDAR, the fiber‑optic radar vehicle positioning and tracking system developed by Jianhe Bafang, is a high‑sensitivity distributed fiber‑sensing solution designed for intelligent traffic road monitoring. It outputs real‑time spatial coordinates of every vehicle across the full road section around‑the‑clock, delivering a brand‑new sensing technology for vehicle‑road cooperation, smart highway construction and urban traffic management.

The FiDAR fiber‑radar system adopts multiple self‑developed core technologies originating from Tsinghua University, including frequency‑tunable light source, ultra‑narrow linewidth laser, semiconductor optical amplifier chip and high‑precision optical coherent detection. Supported by advanced demodulation algorithms, it achieves centimeter‑level high‑sensitivity positioning within a maximum coverage range of 50 km.

Key Product Highlights

1、All‑weather Operation

The system works stably day and night and maintains reliable performance under harsh weather conditions such as rain, snow, fog and strong wind. Compared with conventional cameras and microwave radars, it delivers stronger environmental robustness for year‑round uninterrupted road surveillance.

2、Continuous Whole‑section Vehicle Tracking

Real‑time full‑trajectory tracking is available for all vehicles on the monitored road. A single unit can cover long‑distance road segments without multi‑sensor data fusion, avoiding track‑break risks between different monitoring nodes and greatly improving tracking continuity and data integrity.

3、Energy‑saving Passive Fiber Design for Lower Costs

The sensing fiber is a passive component requiring no power supply along the road. One interrogation unit supports up to 40 km of detection coverage, featuring low power consumption and eco‑friendly performance. It substantially cuts construction investment and long‑term maintenance expenses throughout the project lifecycle.

4、High‑precision Lane‑level Positioning

Sub‑meter positioning accuracy enables the system to accurately identify which lane each vehicle occupies. The lane‑level location data meets strict precision requirements for intelligent‑traffic applications including highway‑flow analysis, illegal‑lane‑change detection, vehicle‑trajectory tracing and vehicle‑infrastructure cooperative perception.

The FiDAR fiber‑optic radar tracking system is well suited for smart highways, urban arterial roads, tunnel and bridge traffic monitoring, acting as a new‑generation highly‑reliable long‑distance sensing foundation for intelligent road networks.
