Textron to provide A²PATS for simulation testing of F-35 EW systems


Textron Systems Electronic Systems is set to supply its advanced architecture phase amplitude and time simulator (A²PATS) for simulation testing of the F-35 Lightning II electronic warfare (EW) systems.

The company will provide complex threat simulation capability for the aircraft at Eglin Air Force base, under a contract awarded by Lockheed Martin.

The F-35 Norwegian, Italian Reprogramming Lab (NIRL) at the air base will use the A²PATS to develop and validate aircraft software requirements.

The A²PATS is a plug and play system that uses identical phase-coherent, direct digital synthetic stimulus instruments (SSI) as the radio frequency (RF) source for all signals.

Textron Systems Electronic Systems senior vice-president and general manager Steve T. Mensh said: “The F-35 is one of the world’s most advanced tactical aircraft, designed to deliver powerful new capabilities to the warfighter.

“Our A²PATS gives the F-35 community the confidence needed to validate mission-critical electronic warfare systems.”

Designed to provide simulation capabilities and reduce life cycle costs, the advanced electromagnetic environment simulator incorporates electronic warfare, communications and electronic intelligence capabilities.

"Our A²PATS gives the F-35 community the confidence needed to validate mission-critical electronic warfare systems."

The threat simulation technology facilitates the testing of precision location, identification and defensive systems against virtually all ground-based and airborne threats.

According to the company, the advanced technology open architecture simulator distributes multiple RF synthesisers in a modular and expandable system.

The F-35 Lightning II is a fifth generation fighter aircraft, whose EW capabilities enable pilots to locate and track enemy forces, jam radars and disrupt attacks effectively.
