The low-altitude flight environment is complex.
Small obstacles such as power lines and tree branches pose major challenges to safe drone flight.
Especially at night, in rain/fog, or under backlight, traditional vision solutions are prone to missed and false detections.
Targeting complex low-altitude obstacle avoidance scenarios, Nanoradar launches the Lingyu series — Micro Drone Obstacle Avoidance Radar UCM611.

| Parameter | Value |
| Detection Range | 40m |
| Ranging Accuracy | ±0.13m |
| Speed Range | ±99km/h |
| Refresh Rate | 20Hz |
| Tracked Targets | 16 |
1. Small Size, Big Performance

Compact 35×35mm design, roughly the size of two coins. Dual wide-angle 120° detection with high resolution enables wire-level obstacle avoidance.
Supports serial port and RS422 for easy integration with flight controllers and drone systems, reducing development complexity.
2. Wire-Level Obstacle Avoidance — Reliable Detection of Small Targets

UCM611 detects thin obstacles like power lines and branches stably at 20m.
Compared to vision — prone to misses in low-texture scenes — millimeter-wave radar offers more stable small-target sensing, providing enhanced drone safety.
Figure: Customer field test data in a high-voltage line scenario.

Field data shows: at a drone flight speed of 2.5m/s and altitude of 53m, the radar still outputs continuous, reliable detection data — demonstrating wire-level obstacle avoidance capability.
3. Real-Time Multi-Target Perception

Tracks up to 64 targets and outputs 16, along with relative velocity to help flight controllers assess collision risk in advance.
Unlike vision/LiDAR (which need multiple frames to estimate speed), millimeter-wave radar responds faster with lower latency.
4. Strong Adaptability for Complex Environments

All-Weather: Operates stably in rain, snow, fog, etc. In heavy rain, range attenuation is only ~30% — significantly stronger all-weather capability than vision-based solutions.
Anti-Interference: 8G wide bandwidth, supports multi-point frequency hopping. Reduces co-channel interference in multi-drone coordination and complex low-altitude environments.
5. Dual 120° Wide Coverage

Horizontal 120° × vertical 120° dual wide-angle detection. Compared to traditional narrow-field radars, significantly reduces blind spots. Effective in obstacle-dense, wire-crossed, close-range turning scenarios.
6. Global Collaboration — Seamless Open-Source Flight Control Integration


Nanoradar is an official partner of four open-source flight control platforms (APM, PX4, FMT, ACFLY). Supports PX4 mainstream hardware (e.g., Pixhawk 4, Cube Orange) and APM hardware (e.g., Pixhawk 2.4.8). Deeply adapted to PX4's MAVLink protocol and uORB framework, and APM's MAVLink driver architecture — plug-and-play, seamless integration.
7. Application Scenarios

Designed primarily for small to medium drone platforms. Widely applicable for energy inspection, emergency response, firefighting, surveying, environmental monitoring, and other low-altitude operations — providing stable, reliable short-range obstacle avoidance perception.
