Current airborne electronic warfare (EW) systems must first identify a threat radar to determine the appropriate preprogrammed electronic countermeasure (ECM) technique. This approach loses effectiveness as radars evolve from fixed analog systems to programmable digital variants with unknown behaviors and agile waveforms. Future radars will likely present an even greater challenge as they will be capable of sensing the environment and adapting transmissions and signal processing to maximize performance and mitigate interference effects.
The goal of the Adaptive Radar Countermeasures (ARC) program is to enable U.S. airborne EW systems to automatically generate effective countermeasures against new, unknown and adaptive radars in real-time in the field. ARC technology will:
ARC technologies will be developed using an open architecture to allow for insertion, modification, and removal of software modules with minimal effect on other elements of the system. ARC algorithms and signal processing software will be suitable both for new EW systems and for retrofit in existing EW systems without extensive rework of front-end radio frequency hardware.
