One of the non-offensive powers available to Wes. Radar Pulse helps Wes locate energy sources, Blast Shards, Dead Drops, and highlights enemies with a Blue Aura for a few seconds. The Radar Pulse is, obviously, some kind of sonar, but how Wes actually does it is not known. It may be that he sends out an electromagnetic pulse that creates an "echo" that he is able to read, but it can also be a result of Wes concentrating for a moment to locate specific electric fields in the area.
