What is the difference between Rafale PESA and AESA radar?
The Rafale PESA (passive electronically scanned array) radar and the AESA (active electronically scanned array) radar differ primarily in their antenna design and operational capabilities. The PESA radar uses a single antenna element with passive samples to electronically steer the radar beam.
It works by adjusting the phase of the signal to the antenna elements to change the direction of the radar beam. In contrast, AESA radar uses numerous small transmit/receive modules (TRMs) that individually control the phase and amplitude of the radar beam electronically.
The AESA radar offers faster beam steering, improved agility and improved reliability compared to the PESA radar due to its distributed architecture and advanced signal processing capabilities.
Which is better, AESA vs PESA radar?
The choice between AESA and PESA Radar depends on specific operational requirements and technological advancements. AESA radar is generally considered superior to PESA radar due to several advantages.
Aesa Radar offers higher reliability and operational flexibility, as it can perform multiple functions simultaneously (such as radar mapping, tracking and jamming) and has faster agility and response times. AESA radars also tend to have better jamming resistance and are easier to maintain due to their distributed design.
However, PESA radars may still be used in certain applications where cost considerations or specific operational requirements make them viable.
Which fighter jets have aesa radar?
Several modern fighter aircraft are equipped with AESA radar systems due to their advanced capabilities and operational advantages. Aircraft such as the F-22 Raptor, F-35 Lightning II, Eurofighter Typhoon and Rafale are equipped with AESA radar technology.
AESA radars provide these aircraft with improved situational awareness, target detection, tracking accuracy and electronic warfare capabilities compared to older radar technologies.
PESA radar systems have disadvantages compared to AESA radars. A major disadvantage of the PESA radar is its limited beam agility and slower beam steering capability. This limitation may affect the radar’s ability to track fast-moving targets or perform rapid scanning across different sectors.
PESA radars also tend to be less efficient in power consumption and may have reduced reliability due to their reliance on fewer antenna elements and passive phase shifters. Additionally, PESA radars may be more sensitive to electronic countermeasures (ECM) and fog compared to AESA radars, which have inherent advantages in electronic warfare scenarios.
