UAM231 High-Precision Millimeter Wave Radar Altimeter for Drone Height Control
The UAM231 altimeter emits a fan-shaped microwave beam downward to detect microwave reflections, identify obstacles below, feed back the relative height between the obstacle and the radar, and guide the UAV to maintain a stable altitude.
Through the design of frequency-modulated continuous wave (FMCW) and the signal processing method of directional static clutter filtering, the UAM231 can reduce the near-field blind zone and output static and dynamic altitude information in real time, ensuring more stable, accurate, and reliable UAV takeoffs and landings. It can effectively help customers confirm the correctness of data, further improve security, and meet the application of various complex environments.
To facilitate customer testing, UAM231 radar provides UART/CAN/RS232/RS422/RS485 communication interfaces. The default rate of the UART interface for board-level communication is 115800 bit/s, the baud rate of CAN communication is 500 kbit/s, and the target refresh rate is 40 Hz. The universal external interface can be quickly integrated with the host computer or other MCUs, reducing user configuration and operational time.
Typical Applications
High-altitude UAVs operate at relatively high altitudes and may traverse various terrain types, resulting in diverse scene changes and significant altitude variations. Traditional sensors are limited by external factors such as weather, altitude, and terrain, and thus cannot provide accurate altitude information for UAVs. In contrast, millimeter-wave sensors—with their high precision, all-weather adaptability, and miniaturization—have become core components for high-altitude UAVs to achieve real-time height measurement and mission execution.In the future, we need to further break through the bottleneck of signal attenuation and cost, and promote the large-scale landing of high-altitude UAVs in meteorological, logistics, security and other fields through multi-technology integration and policy support.
