24GHz Radar Altimeter | High-Precision Altitude Measurement from 0.4–500 m

Model No.: NRA24Pro

This 24GHz radar altimeter is a high-performance altitude measurement sensor specifically designed for low-altitude aircraft and unmanned systems. With a detection range from 0.4 meters to 500 meters, it delivers stable and accurate altitude data even in complex operating environments. Utilizing 24GHz millimeter-wave radar technology, the sensor offers strong anti-interference capability and is unaffected by lighting conditions, fog, dust, or haze, making it suitable for all-weather and all-environment operation.

The radar altimeter supports both UART serial communication and CAN bus communication protocols, enabling flexible integration with mainstream flight controllers and embedded systems. Its low-latency, real-time data output meets the high reliability requirements of flight control systems for altitude information.

In terms of performance, the sensor features high measurement accuracy, excellent repeatability, and fast response time, significantly improving altitude control and flight safety. Compared with traditional barometric sensors or optical ranging solutions, radar-based altitude measurement performs more reliably at low altitudes and over complex terrain or vegetation, making it ideal for applications with strict accuracy requirements.

From a cost perspective, this 24GHz radar altimeter combines performance and reliability with excellent cost efficiency, providing users with an economical and practical altitude measurement solution while reducing overall system costs.
