NRA24PRO High-Precision Millimeter Wave Radar Altimeter for Drone Height Control
NRA24Pro 500m is a compact altimeter radar with 2cm measurement accuracy, compact size, high sensitivity, light weight, easy integration
and stable performance, which can meet the application requirements of unmanned aerial vehicles (UAV/UAS), helicopters, small airships and other fields. Product performance has been recognized by many partners.
Advantages of the NRA24Pro meter:
Accurate height setting and real-time height output;
Light weight, small volume and low power consumption;
The anti-interference capability is strong and the integration is easy;
Multi-interface adaptation, not restricted by terrain, weather and aircraft type;
The NRA24Pro altimeter detects the reflection of the microwave by emitting a beam of fan-shaped microwave downward, judges whether there is an obstacle below, feeds back the relative height of the obstacle and the radar, and guides the UAV to fly at a stable height.
NRA24Pro can make the near blind area smaller through the design of frequency modulation continuous waveform and the signal processing method of directional static clutter filtering, and can output static and moving altitude information in real time to ensure that the take-off and landing of UAV are more stable, accurate and reliable. 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, NRA24Pro radar provides UART/CAN/RS232 /RS422/RS485 communication interfaces. The default rate of UART interface for board-level communication is 115200bit/s, the baud rate of CAN communication is 500kb/s, and the target refresh rate is 40Hz. The universal external interface can be quickly integrated with the upper computer or other MCUs to save the configuration and use time of the user.
