AN/APG-77
From Wikipedia, the free encyclopedia
AN/APG-77 is the designation for the multifunction radar installed on the F-22 Raptor fighter aircraft. The radar is built by a joint venture between Northrop Grumman and Raytheon.
It is a solid-state, active electronically scanned array (AESA) radar. Composed of ~2000 transmit\receive modules, each about the size of a human toe, it can perform a near-instantaneous beam steering (in the order of tens of nanoseconds).
The AN/APG-77 provides a 120° horizontal field of view.
Much of the technology developed for the AN/APG-77 is being used in the AN/APG-81 radar for the F-35 Lightning II.
[edit] Data processing
Radar data in the F-22 Raptor is digitally processed by two polyalphaolefin-cooled Raytheon Common Integrated Processors (CIPs).
