4D Imaging Obstacle Avoidance Radar AFM761
keyword：
Millimeter wave radar series
INTRODUCTION
The AFM761 is a mid-range, high-resolution distance sensor. It emits a conical electromagnetic wave forward, detects the reflected signal, and determines whether obstacles are present ahead. It reports relative distance (length, width, height), angle, speed, and other information about obstacles relative to the radar, accurately alerting the driver during forward driving or reversing. The product adopts a multiple-input multiple-output (MIMO) antenna design, with a measurement range of 0.5–250m. It is compact, highly sensitive, stable, lightweight, and easy to integrate.
Features：
- Detection angle up to 120° for pedestrians within 100m; elevation beamwidth approximately 30°; effectively distinguishes two objects with a radial distance greater than 0.2m
- Outputs obstacle distance, angle, and speed information
- Ranging range 0.5–250m
- Compact size; weighs only 143g; power consumption 3W
- Supports 9–32V wide voltage and CAN-FD interface for easy integration
- IP67 high protection rating; all-weather, all-day protection
Application：
- Forward obstacle avoidance for mining trucks, mixer trucks, excavators, snowplows, driving training vehicles, and other vehicle platforms

ADVANTAGES
 | Long Detection Range, High Resolution, Strong Safety Warning Capability It can detect obstacles up to 250m away, with a distance measurement resolution ≤0.40m and accuracy ≤±0.20m, effectively distinguishing two objects with a radial distance greater than 0.2m. The wide-angle beam design achieves a 120° detection angle for pedestrians within 100m, with a small blind zone, helping drivers judge obstacles ahead in advance and ensuring the safety of vehicles and personnel. |
 | Outstanding Multi-Target Processing and Anti-Interference Capability Supports detection and tracking of multiple targets, continuously providing vehicle, pedestrian, and obstacle information for complex mixed-traffic scenarios. The low-sidelobe antenna design effectively reduces ground clutter and out-of-beam target interference, improving target detection signal-to-noise ratio and accuracy. |
 | Compact Size, Low Power Consumption, Easy Integration Dimensions: 90 × 90 × 24.2mm, it weighs only 143g and consumes only 3W. It supports 9–32V wide voltage and a CAN-FD interface (rates up to 2Mbit/s), allowing flexible integration into mining trucks, mixer trucks, excavators, snowplows, driving training vehicles, and other vehicle platforms for a wide range of applications. |
