Plenty of evidence out there, especially if you match names to patents and see where their internal company promotions took them to. Snippet below, rest at link.

LOBSTAR is a five-year $12 million effort that is a major scale-up of research activity, starting with the ground test in September of the array produced under the S-CLAS programme. A flight test is scheduled for 2008 using Northrop’s BAC One-Eleven testbed aircraft, potentially against real ground targets. The low-band array is focused on detecting and tracking slow-moving targets hidden under foliage, which is not possible using conventional ground moving-target indicator (GMTI) radars. The sensor also can be used for air-to-air tracking.

While LOBSTAR will continue to evolve over the next decade, the more recent X-Band programme has been put on the fast track. In April 2004, the AFRL sensors directorate awarded contracts to Raytheon and Northrop to compete for a new development programme called X-Band thin radar aperture (XTRA), which is focused on producing a synthetic-aperture radar and GMTI sensor for tactical aircraft. The AFRL downselected to the Raytheon proposal in December 2004.

XTRA is another conformal, load-bearing antenna structure that would become part of SensorCraft, but there may be more immediate applications. Perdzock says XTRA “represents more of a transition opportunity”, compared with LOBSTAR, for interim upgrades J-UCAS and manned fighters for which a conventional SAR and GMTI sensors are deemed impractical. These could have access to the new technology after 2012, he says.
