I'm not saying it's new technology. The patriot missile costs $4m each. None of the drones Ukraine is using have this tech.

The new thing is that it's available for purchase for a reasonable price.

Why would they put phased arrays on UAVs? They are typically using beam-forming antennas + cheap gimbals for the same purpose.

Phased arrays are nice when you want to scan a large angular surface very fast; when it comes down to optimizing RF radiation toward your ground station, a gimbal is cheaper, simpler, and works fine.

While it doesn't produce an image, not having 2D data, KrakenSDR has some cool direction finding too.
