Product Description:
Enhance your drone’s safety and navigation precision with the MR72 77GHz 80m UAV Collision Avoidance Radar Module. Designed for advanced obstacle avoidance and reliable distance measurement, this millimeter wave radar sensor provides real-time, accurate detection up to 80 meters with a distance accuracy of 0.1 meters. Equipped with a cutting-edge two-transmitter four-receiver antenna array, the MR72 is capable of tracking up to 128 targets simultaneously, making it ideal for complex and dynamic environments.
Operating in the 77GHz frequency band, the MR72 supports dual mid-long range beam operation, delivering robust performance with high sensitivity and exceptional stability even in harsh weather conditions such as rain, snow, fog, and dust. The device’s compact, lightweight (102x56x16.5mm), and low power consumption (2.5W) design facilitates easy integration with various UAV platforms.
Designed with versatility in mind, the MR72 offers two sensitivity modes — normal and high — allowing users to optimize detection based on the flying environment. The high sensitivity mode is perfect for open areas to detect fine objects like power lines and small branches, while the low sensitivity mode minimizes false targets in cluttered environments. Sensitivity modes can be switched conveniently through PC software or command configuration, eliminating the need to frequently update radar firmware.
The radar module supports full directional obstacle avoidance, and customers can network multiple MR72 units (up to 8 with configurable IDs) to build a comprehensive radar array for 360-degree avoidance coverage. The MR72 also provides seamless integration with APM flight controllers and Pixhawk systems (serial interface version) without requiring modifications to ArduPilot source code — enabling quick deployment with simple parameter settings.
The product comes with proprietary PC software for thorough testing and configuration, ensuring you get the most out of your radar system for UAV applications.
