Next Gen Electronic Warfare will employ multiple beams (U)

Next Generation Electronic Warfare Sense and Attack Systems

• Multiple simultaneous targets present in current environments

• Digital techniques allow efficient scaling to large number of beams (> 2)

• Digital techniques allow neutralization of large number of simultaneous targets (> 10)

• Systems must be lighter and more efficient = more functionality moved on-chip

Active Electronically Scanned Array (AESA) Enables Near-SimultaneousMulti-Mission Capabilities

• Air-to-Air and Air-to-Ground with One Search-Track Mode• Detect/Track Multiple Targets

• Connectivity with On-board and Off-board Sensors

• AESA Transmitters enables simultaneous protection of the Strike Package

Next gen military systems will require a 10x-100x leap in processing power efficiency

Next gen systems require 30 – 300+ GOPS/W in processing power efficiency

Growing gap in processing power efficiency between on-board DoD needs and current technology

≥130 nm 90 nm 65 nm 45 nm 32 nm

• Due to overall system and interconnect complexity, systems generally lag state of the art processor power efficiency.

• Year for system is when introduced, with the caveat that the date becomes updated when components are upgraded.
