On 22 June 2005, Spacewar reported:

Researchers at the National Nuclear Security Administration’s Sandia National Laboratories flew what is probably the world’s smallest fine-resolution synthetic aperture radar (SAR) in May, making real-time images from the 6-kilometer range with a resolution of four inches.

It was a first for the 25-pound instrument that may soon be used for reconnaissance on near-model-airplane-sized unmanned aerial vehicles…

MiniSAR is less than one-fourth the weight and one-tenth the volume of SARs that currently fly on larger UAVs such as the General Atomics’ Predator.

It has the same capability as the larger SARs of making fine-resolution images through weather, at night, and in dust storms.
