Dual Wide-Angle Obstacle Avoidance Radar SR71
keyword：
Millimeter wave radar series
INTRODUCTION
The SR71 is a compact 77GHz short-range radar designed for low-to-medium-speed obstacle avoidance. It emits a conical electromagnetic wave to detect reflections, identifying obstacles and providing precise data on relative distance, angle, and speed. During forward or reverse motion, it delivers accurate obstacle alerts, enhancing driver safety.
Features：
- Horizontal + pitching 120 ° double wide-angle detection;
- Detection distance of 20 m, supporting 64 targets/frame detection and tracking
- Supporting a variety of mounting brackets, easy to install
- Small size, easy to integrate, beautiful installation
- 4D detection, accurate detection of target distance, speed, angle, height information
- IP67 high protection level, all-weather and all-day protection
Application：
- Low-speed vehicle scenarios such as unmanned sweeper, environmental protection vehicle, unmanned shuttle vehicle and mine car

ADVANTAGES
 | Dual Wide-Angle 3D Detection 120° horizontal and vertical FOV. Height filtering eliminates elevated objects (e.g., bridges, traffic lights, signs), while ground clutter algorithms suppress false alerts. |
 | Customizable Alert Zones Define detection parameters by speed, zone, and angle to focus on critical areas. Supports three customizable warning zones with escalating alerts based on target proximity. |
 | Resilient in Harsh Environments IP67-rated. Operates reliably in salt fog, rough terrain, mud, or dusty industrial sites. Immune to light, dust, rain, snow, fog, and sandstorms. |
