The satellites are presumably the "FIA-Radar" (Future Imagery Architecture - Radar) radar component of the FIA system. They are the successors of the Lacrosse / Onyx radar satellites. No details have been published.
The development contract for the Future Imagery Architecture program, consisting of an optical (FIA-O) and a radar (FIA-R) component, was awarded to Boeing in 1999. After running into massive cost overruns and delays of the delivery date of the FIA-O component, in September 2005 the contract for the electro-optical satellites was cancelled. The FIA-Radar satellite program remained at Boeing.
The first satellite was launched in 2010, at least four years behind the original schedule.
