(1) Q: What about the angle accuracy of NRA24?

A: NRA24 is a 24GHz millimeter radar altimeter with 1T1R antenna, it cannot measure the target angle.

For the radar with more than two receiving antennas, it has the ability to measure the angle. Besides, the more antennas it has, the higher accuracy of angle resolution it could realize.


(2) Q: What is the height accuracy of NRA24 at a height of 0.5 meters?

A: TNRA24 adopts one transmitting and one receiving antenna, and the separation design of antennas makes the radar have a high isolation in transmit / receive link, to improve the dynamic range of radar target detection.

At the same time, NRA24 utilizes the advanced integrated planar microstrip array antenna, which contains 40 vertical polarization radiation units for transmitting and receiving antennas.

Therefore, it could achieve height accuracy during the effective measurement range of 0.1-50 meters.


(3) Q: In the height measurement, when there is vegetation and ground, which will it be subjected to? When there is water on the ground, which will it be subjected to, the ground surface or water surface?

A: In practical application, if the height is less than 3m, there would be great air flow below the plane, and the vegetation is likely to be blown away, so the reference point is the ground or water surface.

If the airplane reaches over 5m, the airflow would not affect the vegetation below.

And in case that the vegetation density is large, then the reference point should be vegetation.
