TOOLS & INSTRUMENTS

Large Aperture Scanner

Large Aperture Scanner

The Large Aperture Scanner (LAS) scans a radar transceiver over a 5 meter by 20 meter aperture.  Image reconstruction techniques enable a three-dimensional holographic image of objects in front of the scan aperture to be formed from data collected by the radar transceiver.

Specifications/Capabilities

Transceiver:  200 MHz to 4.6 GHz

Scanner:  5 meters horizontally; 20 meters vertically

Scientific Opportunities/Applications

Imaging through building material

Concealed object imaging/detection

The LAS is used to conduct research in the STG through-barrier imaging laboratory and is also transportable for offsite/field testing
