Dr. Peter Craig, Electronic Warfare ONR312 Program manager writes in the Fall 2012 ONR Innovaiton Newsletter:
"The S2 system “creates a super-vision of the EMS where such signal techniques as frequency hopping, chirping, or spectrum spreading become visible as patterns in a real-time frequency map… This ONR investment has resulted in a system that can simultaneously monitor all EMS emissions over a span of 40 GHz while resolving signals that are separated by only a few 10s of kilohertz – and continuing research will increase this span to greater than 100 GHz.”
