Upgraded PS-05/A radar gives Gripen C/D extended performance, operating range

The PS-05/A Mk4's hardware configuration with a new radar back-end gives improved radar performance and operational range, says Saab.

Defence and security company Saab has developed the PS-05/A fighter radar to a new version designated Mk4, which gives Gripen C/D improved performance and operating range. The development is a significant step on the roadmap for the future capability enhancement of the Gripen C/D.

The PS-05/A Mk4 is the most recent development of the renowned PS-05/A radar, originally developed for the Gripen fighter. Through continuous spiral development, it has maintained its position as one of the most competent fighter radars in the world.

A new hardware configuration with a complete new radar back-end gives significantly improved radar performance and operational range, enhances the Gripen Weapon System capabilities and offers full AMRAAM and Meteor integration. It also enables significant capability growth through software upgrades to successfully counter evolving threats in decades to come.

A new air-to-air mode has been implemented and demonstrated, which takes full advantage of the signal processing capacity and the flexible waveform generation in PS-05/A Mk4. This mode increases acquisition range, with 100% at low altitudes compared to previous version of PS- 05/A. This radar mode will also be useful for detection of targets with very low radar cross-section. The Meteor missile downlink is optimised to maintain radar performance during long-range data-linking scenarios.

"The Mk4 is a world-class multifunction radar, with excellent ECCM performance, growth capability and with very low life cycle cost," says Lars Tossman, head of Airborne Surveillance Systems at Saab business area Electronic Defence Systems.

With the new Mk4 upgrade, the PS-05/A will continue to improve operational capabilities for customers around the world. The PS-05/A Mk4 can be adapted to fit into most airborne platforms. Both compact and lightweight, this modular solution is ideal for integration with standard avionics technology systems and allows for installation on any multi-role combat aircraft, UAV, advanced jet trainer or other airborne platform.
