- jvanderbot 2y agoIt's difficult to tell from the three page datasheet what effective range I would get. But that's a starting point at least.
- solardev 2y agoAs other posters mentioned, you would probably quickly run into FCC issues trying to scale up the radar to something powerful enough to reach across a lake. Probably one of the other solutions (LIDAR, machine vision in the visible, etc.) would be better for that? Or if it doesn't have to be all the time, maybe just hover a drone above them and record downwards?
- jvanderbot 2y ago"Just hover a drone over them and record downwards" seems a lot harder! What a world where that's considered easier than other sensing options. I think vision is a good plan for a lake, with wide baseline. It's not great for a street with oncoming traffic. Turns out, however, that there are COTS radars that will work in the <100m range so I might go that route for the house, and try vision for the lake.
