Keeping pace with the technology trend, Saab’s JAS39 Gripen is to be fitted with a multi-channel active electronically scanned array (AESA) radar, likely to be introduced under a planned mid-life upgrade (MLU) that could come along as early as 2010.
Development of the AESA radar for Gripen started out under the Saab Ericsson NORA (Not Only a RAdar) programme, and has been underway for several years, including test flying aboard a specially-retained Saab JA-37 Viggen testbed. One of the main benefits of the NORA concept was the provision of improved long-range tracking as a result of the combination of longer detection range and electronically-steered beam control. The AESA radar programme is directly linked to MIDAS (Multifunction Integrated Defensive Avionics System), which will also add electronic attack and advanced datalinking capabilities.
Radar upgrades for in-service Gripens are already underway and the AESA project is planned to follow the current Mk.IV upgrade for the type’s Saab Ericsson PS-05/A pulse-doppler radar, which adds precision strike modes and improved synthetic aperture radar (SAR) capability.
The AESA developments are being lined up for what is now being dubbed the ‘Next Generation Gripen’ programme, notably including the proposed variants to meet F-16AM/BM replacement requirements for Norway and Denmark, known as Gripen N and Gripen DK respectively. An AESA version of its current PS-05/A radar, which, can reportedly track airborne targets at distances of up to 120km would provide enhanced multi-mode capabilities for Gripen-NG, as well as extended range for beyond-visual-range (BVR) missiles.
Looking further ahead, Saab Microwave Systems, Selex Sistemi Integrati and Elettronica are involved in the development of the next generation of microwave multi-function, multi-role systems under the multi-role active electronically scanned antenna (M-AESA) programme. The introduction of M-AESA technology will greatly increase the potential of microwave system performance, boosting the ability to detect, track and identify small targets even in the most confused battlespace.
