Small, Cheap, AESA Radars Available for RPVs.

Truth be told, I could see these entering civil aviation as weather radars too, and with a bit of software, you could put it on a cruise missile, and you could follow terrain, and jam radars searching for you.

The PicoSar(Shown below) weighs less than 25 pounds and is about the size of a toaster.

It has a range of about 12 miles and can track ground targets, and it appears to run cool enough that it does not need liquid cooling.



With some decent software, you could probably gang a bunch of these together for better resolution, or use it for stealthy radar antenna.

I'm waiting for someone to apply a low performance (cheap) version of this technology to satellite TV receivers. It could adjust to gusts in fractions of a second.
