The AN/APY-9 Radar is an Active Electronically Scanned Array (AESA) pulse Doppler Ku band multi-mode radar developed and manufactured by Lockheed Martin for the E-2D 'Advanced Hawkeye'.
Capabilities
The AN/APY-9 Radar is designed for Airborne Early Warning and Control operations onboard the E-2D 'Advanced Hawkeye', guiding both surface fleet and airborne assets of the United States Navy. It was designed to detect, track, and identify air and surface targets in blue-water, littoral, and overland environments, and is capable of guiding munitions launched by other ships and aircraft through datalink.[1][2]
The radar system is capable of operating in multiple modes to track different classes of target in a 360° environment using mechanical scanning modes, or providing augmented tracking in 90° sectors by utilizing its AESA capabilities.[3]
The system is all-weather, and can utilize its 'Space-Time Adaptive Processing (STAP)' architecture to suppress jamming, clutter or other sources of electromagnetic interference.[3]
Composition
The radar antenna consists of a group of horizontally polarized Yagi antennas of different lengths and High Power Solid-State transmitters, open architecture and Circuit Card Assembly hardware architecture.[4][3]
