The AN/APG-79

The AN/APG-79 Active Electronically Scanned Array (AESA) radar system

is an advanced Active Electronically Scanned Array (AESA) radar system primarily developed by Raytheon for use in modern military aircraft. AESA radar technology offers several advantages over traditional mechanically scanned radar systems, such as improved performance, higher reliability, and greater flexibility.

Key features and capabilities of the AN/APG-79 radar system include:

1. Active Electronically Scanned Array (AESA) Technology: AESA radars use a grid of tiny transmit/receive modules to emit and receive radar signals electronically, rather than relying on a mechanically rotating antenna. This allows for faster beam steering, improved target tracking, and the ability to perform multiple functions simultaneously.

2. Multi-Mode Operation: The AN/APG-79 radar is designed to support a range of operating modes, including air-to-air, air-to-ground, and air-to-sea capabilities. This flexibility allows the radar to perform various missions without the need for extensive hardware modifications.

3. High Resolution and Precision: AESA technology enables the radar to provide high-resolution imagery and precise target tracking. This is particularly valuable for identifying and engaging small or stealthy targets.

4. Electronic Counter-Countermeasures (ECCM): AESA radars have built-in ECCM capabilities, meaning they can quickly adapt to countermeasures and maintain effective radar performance even in the presence of jamming or other electronic interference.

5. Low Probability of Intercept (LPI): AESA radars can reduce their transmitted power and employ various techniques to minimize the chances of detection by enemy radar warning receivers, making it difficult for adversaries to determine that they are being tracked.

6. Synthetic Aperture Radar (SAR): Some AESA radar systems, including the AN/APG-79, can operate in SAR mode, allowing them to generate high-resolution ground imagery by using the motion of the aircraft to simulate a larger antenna.

7. Long Range: AESA radars generally offer longer detection and tracking ranges compared to traditional radar systems, providing an extended “look-ahead” capability for pilots.

The AN/APG-79 radar is well-known for its use in the Boeing F/A-18E/F Super Hornet and the EA-18G Growler aircraft. The Super Hornet is a multirole fighter aircraft used by the United States Navy and other air forces, while the Growler is an electronic warfare aircraft also based on the Super Hornet airframe.

Overall, the AN/APG-79 AESA radar significantly enhances situational awareness, target identification, and engagement capabilities for the platforms it equips, contributing to the effectiveness of modern military operations. Keep in mind that my knowledge is based on information available up until September 2021, so there may have been further developments or changes since that time.
