... Jamming larger computer processors with more capability into the cabin was not an option. The problem was solved by introducing space-time adaptive processing (STAP).
This is a technique that uses algorithms to isolate clutter and either intentional (jamming) or unintentional interference. The algorithms separate moving targets from static noise, allowing the radar to "see" clearly even amid dense clutter and high power levels.
"It takes in all the background clutter and jamming and adjusts automatically the gain and phase of the antenna such that it optimally cancels clutter and jamming at the same time," Culmo says.
By adding STAP techniques, Northrop solved another problem in the quest to insert a package of modern AEW capabilities into the Hawkeye platform. STAP has been in testing for a decade, with a Lockheed Martin NC-130 equipped with a saucer-shaped radome serving as the testbed. ...
