INTRODUCTION
NanoRadar 77GHz obstacle avoidance radar is suitable in automatic obstacle avoidance for UAV autonomous flight and fixed-point cruise in all-weather, all-time and all-terrain. It supports simultaneous output of distance, speed and angle information of up to 64 target. Featured with low-cost, high accuracy, small& light and low power consumption, MR72-UAV is applicable in agriculture, power, industry, small airship and other fields.
Features：
- Work in 77GHz Band
- Dual beams (short and middle range) operate simultaneously
- With CAN interface
- With measurement accuracy of 0.1m
- Detection range up to 80m
- Detection of up to 64 moving objects
Application：
- UAV safety ranging and anti-collision

ADVANTAGES
 | Dual-Beam Precision Obstacle Avoidance A 14° elevation angle (lower than competitors' 30°) reduces ground clutter interference. With 900MHz bandwidth, it offers 3x better resolution than 24GHz radars, ideal for power line inspections and agricultural obstacle avoidance. |
 | Compact, Lightweight, and Easy to Use Compact size(100 × 57 × 16.5mm) fits various drones, saving space. Weighing only 90g, it minimizes payload. Universal UART/CAN interfaces enable quick integration. |
 | Stable Performance in Harsh Environments IP66-rated, it operates reliably in rain, snow, fog, and dust, with minimal false alarms. |

FAQ
MR72/MR82 | Identifying and Resolving Fixed False Targets
If false targets persist at specific distances without physical obstructions or installation interference:
Upgrade firmware for algorithmic fixes.
Replace the radar if unresolved.
MR72/MR82 | Open-Source Flight Controller Versions
It provides two firmware versions for open-source flight controllers, based on v3.6.0 (divided into pre-3.6.0 and post-3.6.0). Note: Only UART is supported (not CAN). Flight controller parameter modification guidance is available.
MR72/MR82 | Verifying Radar Operation
With stable power and correct wiring, if the host shows no output:
Use a serial port tool or CANtest to check raw data output.
Verify data format compliance with the protocol.
Inspect LEDs D3 (fast blink) and D4 (steady light) for normal operation.
