AN/APG-70

1. 본문

The AN/APG-70 is a family of all-weather, multimode radar systems designed by Hughes Aircraft (later Raytheon) for the F-15 Eagle fighter aircraft. It's an X-band pulse-Doppler radar used for both air-to-air and air-to-ground missions.

Here are some key features and facts about the AN/APG-70:

• Improved Design: The APG-70 was a redesign of the earlier AN/APG-63 radar, focusing on greater reliability and easier maintenance.
• Enhanced Capabilities: It incorporated gate array technology, enabling new modes and enhanced operational capabilities compared to its predecessor.
• Target Detection: It can detect and track aircraft and small, high-speed targets at various altitudes, from treetop level to beyond visual range.
• Weapons Delivery: The radar provides target information to the aircraft's central computer, aiding in effective weapons delivery. In close-range dogfights, it can automatically acquire enemy aircraft and project information onto the cockpit's head-up display.
• Commonality: To reduce costs, many of the APG-70's modules are shared with the F/A-18's APG-73 radar, and its computers/processors have 85% commonality with the F-14's APG-71 radar.
• Variants:
• APG-70(V): An improved version for the F-15E Strike Eagle.
• APQ-180: A derivative of the APG-70, designed for the AC-130U gunship. It includes enhanced air-to-ground modes.
• Performance: The APG-70's signal processor uses modular parallel processing and it was designed to operate at speeds at over 30 million complex operations per second.
• Replacement: The mechanically scanned APG-70 has been replaced on F-15E's by the active electronically scanned array (AESA) system, designated as the APG-82(V)1.
• Aircraft: The APG-70 was installed on later model F-15C/D aircraft (now replaced by the APG-63(V)1), F-15E Strike Eagle, Israeli F-15I, and Saudi F-15S.
