Choosing radar for ardupilot

I going to use radar for object avoidance. I’m considering some things like ulanding (US-D1), NRA24 and 77Ghz millimeters (foxtech) or MR72, but I’m not sure about that. (detecting range of at least 20 to 30 meters)
Please let me know if you have any experiences or suggestions. (Compatible with pixhawk and ardupilot)

Start with the Wiki page:

Yes I read it, It is recommended to use US-D1 radar but it’s for Altimeter (downwards). I’m looking for Collision Avoidance radar.
I think the mr72 radar is good but I’m not sure.

A bit off topic, where did you read that US-D1 is reccomended? I can’t find it and i would like more info about that radar.

I don’t know about recomended but here is some info about that radar altimeter. They say Plug and Play via UART for Ardupilot.

thanks my issue has been fixed.

Yes, maybe I’m wrong about Altimeter.
I say that because it’s known by altimeter radar and in some cases write it used to take off, landing and terrain tracking.
Please share if you have any information or experience in this regard.
