| - The AN/APG-77v1 is the AESA radar monted on the F-22 Raptor it has about 2300 transmit/receive moduls and it´s able to track a 1 square meter target at 350-400 km a 1 m² target. The AN/APG-77 AESA radar, designed for air-superiority and strike operations, features also a low-observable, active-aperture, electronically-scanned array that can track multiple targets under all weather conditions. The AN/APG-77 changes frequencies more than 1,000 times per second to reduce the chance of being intercepted, the APG-77 is one of the key features to the F-22 Raptor's so-called "first look, first shot" capability.
- The AN/APG-77 is a multifunction radar installed on the F-22 Raptor fighter aircraft. The radar is built by Northrop Grumman. It is a solid-state, active electronically scanned array (AESA) radar. Composed of 1500 transmit/receive modules, each about the size of a gum stick, it can perform a near-instantaneous beam steering (in the order of tens of nanoseconds). More than 100 APG-77 AESA radars have been produced to date by Northrop Grumman, and much of the technology developed for the APG-77 is being used in the APG-81 radar for the F-35 Lightning II.

- The AN/APG-77 is a multifunction radar installed on the F-22 Raptor fighter aircraft. The radar is built by Northrop Grumman. It is a solid-state, active electronically scanned array (AESA) radar. Composed of 1500 transmit/receive modules, each about the size of a gum stick, it can perform a near-instantaneous beam steering (in the order of tens of nanoseconds). The APG-77 provides 120° field of view in azimuth and elevation,[citation needed], which is the highest possible value for a flat phased array antenna. As yet unconfirmed sources suggest that APG-77 has a 'typical' operating range of and is specified to achieve an 86% probability of intercept against a 1 m2 target at its maximum detection range using a single radar paint. Other source described only as being more than . However, it's thought to be closer to , which is much farther than the standard F-15's radar range More than 100 APG-77 AESA radars have been produced to date by Northrop Grumman, and much of the technology developed for the APG-77 is being used in the APG-81 radar for the F-35 Lightning II. The APG-77v1 was installed on F-22 Raptors from Lot 5 and on. This provided full air-to-ground functionality (high-resolution synthetic aperture radar mapping, ground moving target indication and track (GMTI/GMTT), automatic cueing and recognition, combat identification, and many other advanced features).
