searching for obstacle sensor with high distance detectiion (20M+)

Hello guys and girls i'm asking for your help after all my searches didn't give me any results for my needs.|
i'm searching for obstacle\proximity sensor that can detect obstacles withing high distance spectrum (20 meter + minimum 15 meter) i will favor a proximity sensor that can give me some feedback about object distance (+-7 meters resolution).
if you have any OEM product or any guide how to make such thing i will be really great-full.

thank you and greetings from israel :slight_smile:

0 to 40 meters with ~3 cm resolution.
