The AN/APG-77 is a multifunction low probability of intercept radar installed on the F-22 Raptor fighter aircraft. The radar was designed and initially built by Westinghouse and Texas Instruments, and production continued with their respective successors Northrop Grumman and Raytheon after acquisition. It is a solid-state, active electronically scanned array (AESA) radar. Composed of 1956 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).

- AN/APG-77은 레이시온사가 개발한 AESA(Active Electronically Scanned Array 한국어: 능동 전자주사식 위상배열) 레이다이다. 종래의 기계식 레이다처럼 송신부와 수신부가 따로 되어 회전하는 게 아니라 작은 송수신 통합 모듈 수천 개가 붙은 레이다 전반부가 고정된 형태에서 각종 기능을 수행한다. 아울러 회전하지 않더라도 충분한 영역을 커버할 수 있다. APG-77은 기계식에 비해 손색없는 정면으로부터 약 120도의 탐지범위를 갖고 있다. 또한 기계식과 달리 목표물이 탐지될 경우 아주 신속하게 소프트웨어의 작동만으로 전자적으로 레이다빔을 증가시키거나 방향을 전환시킬 수 있다. 고속기동하는 물체를 추적하는 능력도 훨씬 뛰어나다. 레이다의 전면부에 220개의 송수신 모듈(Transmitter-Receiver Module)이 부착되어 있는데 모듈 1개의 무게는 15g이지만 신호는 4W의 강력한 신호를 내뿜는다.또한 이 레이다는 다른 레이다 전파를 역탐지할 수 있으며,AN/APG-77은 레이다가 상대에게 역탐지되지 않는 장점이 있다. 현재 F-22 랩터에 탑재되어 사용 중이다.

| - The AN/APG-77 is a multifunction low probability of intercept radar installed on the F-22 Raptor fighter aircraft. The radar was designed and initially built by Westinghouse and Texas Instruments, and production continued with their respective successors Northrop Grumman and Raytheon after acquisition. It is a solid-state, active electronically scanned array (AESA) radar. Composed of 1956 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,. APG-77 has an operating range of 100 mi (160 km) while unconfirmed sources suggest an operating range of 125–150 mi (201–241 km), against a 1 m2 (11 sq ft) target. A range of 400 km or more, with the APG-77v1 with newer GaAs modules is believed to be possible while using more narrow beams. 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 system itself exhibits a very low radar cross-section, supporting the F-22's stealthy design. 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).
