August 2006 ImSAR and Insitu announced the completion of a prototype
development of a one-pound synthetic aperture radar (SAR) system
called NanoSAR. The system could enable all-weather reconnaissance and
geolocation capabilities of Synthetic Aperture Radar to almost all
airborne platforms, including lightweight Unmanned Aerial Systems such
as Insitu's ScanEagle.
According to the partners, the partnership
between ImSAR and Insitu ensured the technology is smoothly and
successfully integrated into Insitu's UASs without interoperability or
other technical issues.
The new SAR operates on the X band, mapping
an area in a "stripmap" mode at a range of one kilometer, at
resolution of 35cm (14x14"). The system will support broad area
reconnaissance and Search and rescue operations in its basic
configuration and offer optional expansions including Geolocation
mode, cueing GPS guided munitions, and automatic detection of ground
targets, utilizing Ground Motion Target Indication (GMTI) functions.
