Combat systems
The Raptors combat computer systems and power are unmatched by any
other fighter planned to be developed by 2020. The AN/APG-77 AESA
radar, designed for air-superiority and strike operations, features
a low-observable, active-aperture, electronically-scanned array
that can track multiple targets in all kinds of weather. The
AN/APG-77 changes frequencies more than 1,000 times per second to
reduce the chance of being intercepted. The radar can also focus
its emissions to overload enemy sensors, giving the plane an
electronic-attack capability.[4]
The radars information is processed by the two Raytheon-built
Common Integrated Processor (CIP)s. Each CIP operates at 10.5
billion instructions per second and has 300 megabytes of memory.
Unprecedented amounts of information can be gathered from the radar
and other onboard and offboard systems, filtered by the CIP, and
offered in easy-to-digest ways on several cockpit displays,
enabling the pilot to remain on top of complicated situations. The
Raptors software is composed of over 1.7 million lines of code,
most of which concerns processing data from the radar [5].
