So would this mean that with a few more transmitting and receiving antennas it could have comparable resolution to lidar?

- itishappy 3y agoIn theory, though it sounds like to compete with LIDAR it will need about 1000x more antennas, with a related increase in electronics.
- user_7832 3y agoAny idea if these antennas can be made small/on a PCB, effectively miniaturizing them?
- beeeeerp 3y agoCutting-edge AESA radar like on the F-35 is incredible. It actually looks like a black and white photograph. I think your guess on antennas is roughly correct based on what we know about modern AESA.
- KeplerBoy 3y agoIsn't that Synthetic Aperture Radar though? You can get similar results (black and white aerial pictures) by strapping a pretty basic siso radar system on a drone.
- beeeeerp 3y agoI’m honestly not sure what the difference is. I kind of understand SISO, MIMO, and beam steering concepts, but just the basics from nerding out on my Starlink dish. This is what I’m talking about: https://www.twz.com/f-35-will-get-new-radar-under-massive-upgrade-initiative https://www.twz.com/f-35-will-get-new-radar-under-massive-up...

It blows my mind.
