They aren't really specific about how the camera works. I wish
however they would stop pretending resolution is proportional to pixel
count instead of being regulated by linear pixel count.

Doubling resolution, being able to see an object 1/2 the size of that
just seen requires that the linear pixel count be doubled. This is a
quadrupling of pixel count of the sensor. A doubling of the pixel count
(e.g. from 12 to 24MP) only increases resolution by 50%.

Oh I see - 41% really.

And not even that if the lens is crap. I have a "lipstick" video camera,
with "full HD" video, that is well below decent SD video quality even when
recording 1920x1080p. :-(

According to DARPA, it's a system
"...that provides the warfighter a minimum of 65 VGA video windows
across the field of view."

<http://www.darpa.mil/>, search for "argus-is"

Which sounds like multiple smaller sensors. The accompanying sample
image seems to show stitching artifacts, as well.

Ah, as usual, Aviation Week has the dope:

The 1.8-gigapixel sensor has four optical telescopes, each with 92
5-megapixel focal-plane arrays - cellphone camera chips, says
BAE. The airborne processor combines the video output from all 368
arrays together to create a single mosaic image, with an update rate
of 12-15 frames a second.

<http://www.aviationweek.com/>, search for "argus-is", choose "blogs".
