Description

If human ears could hear the electromagnetic spectrum, the noise levels these days would be overwhelming. The skyrocketing use of wireless devices in military and civilian domains has created a complicated and cacophonous environment, filled with signals of widely varying frequency and amplitude and a menagerie of modulations. For warfighters trying to maintain critical communications links, interpret ambiguous radar returns, or defend against electronic warfare tactics, the ability to sort through that thicket of waveforms is essential—to identify where key signals are coming from, what kind of signals they are, and how best to send and receive information via the least contested spectral bands.

Toward that end, DARPA earlier this month hosted the Battle of the ModRecs—a low-key competitive opportunity for engineers with a penchant for antennas and algorithms to test their skills in modulation recognition.
