Saab has unveiled a previously closely held program that puts the company ahead of most of its larger rivals in the race to field active electronically scanned array radars and electronic warfare (EW) systems based on gallium-nitride (GaN) technology. The company is deploying GaN in a new and expanded range of land- and sea-based radars and in the EW system of the JAS 39E Gripen fighter. Longer-range radars using GaN are expected to show much better detection performance against stealthy targets than current products, and-in a follow-on development-Saab technologists are looking at teaming active long-range radars with passive receivers, further improving counter-stealth capability. GaN technology likely will also be used in future upgrades of the EriEye airborne warning and control system.
