Harris Corp. received a contract from Lockheed Martin to continue development of the flight demonstration system radar payload for the Innovative Space-Based Radar Antenna Technology (ISAT) program, Harris announced June 16.

The ISAT program includes the development of the technologies required to deploy extremely large antennas in space for tracking moving targets on the ground. Harris is responsible for the design of the radar sensor payload, which will provide moving target surveillance of areas aircraft cannot cover. Harris completed three prior contracts for earlier phases of the ISAT program.

The ISAT program is run by the U.S. Defense Advanced Research Projects Agency Special Projects Office and the U.S. Air Force Research Lab‘s Space Vehicles Directorate.

The value of the contract was not disclosed.
