Typhoon E-Scan Radar

Recommended Posts

BAE Systems says the Typhoon E-Scan will “deliver the largest electronically scanned array for increased detection and tracking ranges, advanced air-to-surface capability and enhanced electronic protection measures. The large airframe also allows a wider field of regard than any other platform.” 



The antenna at the front-end of the E-Scan is mounted on a swashplate repositioner, that allows a much wider field-of-regard in terms of angular coverage (azimuth) compared with a fixed-plate antenna. It provides the ability to slew the antenna to “look” at far greater angles off the centerline of the aircraft. As such, a Typhoon could be traveling perpendicular to its target while still maintaining lock. This unique capability enables some highly unique tactics, which can be especially for non-stealthy fourth-generation fighter aircraft.

Eurofighter says “The Captor-E electronically scanned radar is the future primary sensor on Eurofighter Typhoon and has a full suite of air-to-air and air-to-surface modes. The capacious aperture of the Eurofighter Typhoon allows the installation of Captor-E’s optimized and repositionable array whose field of regard is some 50 percent wider than traditional fixed plate systems.” A different repositioner system that looks to achieve the same goal is used by the Saab JAS 39 Gripen E for its Leonardo ES-05 Raven AESA radar.

One Radar Becomes Three

Details regarding the Captor-E test program since 2016 have been limited, although in Italy, Leonardo’s test aircraft Instrumented Series Production Aircraft 6 (ISPA 6) was reconfigured to full Kuwaiti Air Force standard and it returned to flight on December 23, 2019, to commence trials from Leonardo Aircraft Division in Turin-Caselle, Italy. 

The aircraft became the third to carry the Captor-E and it is in Phase 3 Enhancement Package b (P3Eb) standard, which is the latest multi-role configuration — the standard specified for Kuwait. Eurofighter said that ISPA 6 has been used to refine Electronic Counter-Countermeasures (ECCM) for the radar and for software release certification flights.

While the baseline Captor-E is an integral part of the four-nation development program for the Eurofighter, there are actually three different variants of the radar. Kuwait and Qatar will receive the Mk 0 version, which was previously known as “Radar 1+.” The order for Germany and Spain will deliver 110 Mk 0 systems, but they will be subsequently upgraded to Mk 1 standard, which is a step-up in capability.

Leonardo remains the industry lead on the Captor-E Mk 0 radar and the company will provide “knowledge transfer” to enable Hensoldt to assume the role of design authority for the Mk 1 upgrade, with Leonardo continuing to provide the processor for this radar variant. The upgrade is thought to include the provision of new Transmit-Receive Modules (TRMs) for the antenna and a new multi-channel digital receiver. This is to be embodied initially as an upgrade and then via new-build radars.

If i remember correctly the soviets showed their first AESA Radar during Le Bourget Airshow in 1988 or 1989 on board of a MiG-31. What means: Wow!!! The EuFi now get what the soviets had already had 30 years ago!

I think the operational MiG-31s have a passive (PESA) antenna. The early Rafales have PESA. From 2014 the F3+ standard Rafales have an active (AESA) antenna. 

The F-22 was the first fighter with an AESA antenna.
