STARLOS

Resolution: 6 in

Early SAR systems required a great deal of payload volume, mass, and power to produce near real-time SAR image products while on board the host aircraft. This early SAR weighed 500 lbs. and could only be loaded onto large and heavy platforms. In addition, a radar operator and image analyst(s) were required on-board.

Size:
8 ft3
Weight:
500 lbs. (total weight - gimbal pictured was only about 160 lbs.)
Power:
3500 W - 3 kW (complete system)
Intel Products:
Near Real-Time Processing / Stripmap SAR / Spotlight SAR
Platform:
DOE Twin Otter (radar was also altered for other platforms)

1996

X-Band Radar System

Resolution: 6 in

Initially, high-quality X-Band SAR imagery was desired for target characterization and template generation. Later, upgrades expanded the sensor capability to include polarization diversity which was originally of interest for bistatic SAR investigations. Modern, miniaturized (miniSAR variant) Sandia X-Band radar systems are being utilized for detecting visually obscured crevasses in Antarctica in support of the National Science Foundation.

Size:
Two 4 ft 19 in tall equipment racks, plus one TX/Antenna/Gimbal assembly (~4 ft3)
Weight:
400 lbs.
Power:
~2 kW
Intel Products:
Near Real-Time Processing / Stripmap SAR / Spotlight SAR / Polarimetry
Platform:
USAF LC-130, DHC-6 Twin Otter
