The US Air Force announced that Lockheed Martin has been selected to continue
development of the Innovative Space Based Radar Antenna Technology, known as
ISAT. The contract, valued at $19.5 million, is for the next phase of the
Defense Advanced Research Project Agency's (DARPA) ISAT project, administrated
by the Air Force Research Laboratory (AFRL).
Lockheed Martin will continue development of the ISAT Flight Demonstration
Experiment design over the next 14 months, which will take it to the Critical
Design Review (CDR) maturity level. Following the CDR, DARPA and the Air Force
plan to select a contractor to build and deploy a scale version of the antenna
for a one-year proof of technology experiment in low earth orbit.
The objective of the ISAT program is to create and demonstrate technology for
very long space-borne electronically scanning antenna. The demonstration
experiment will use an antenna extending about 100 meters (325 feet) in length;
the full scale version is designed to extend 300 meters.
The full scale antenna payload would be folded up to about the size of a sport
utility vehicle and placed inside a payload fairing atop the launch vehicle.
Once deployed in space, the antenna's length would be similar to the height of
the Empire State Building. Such a lightweight and lengthy antenna could
significantly increase global persistent surveillance coverage.
