Echodyne helps DARPA with drone tracking test

When the Pentagon’s Defense Advanced Research Projects Agency tested an “Aerial Dragnet” system for tracking drones over urban terrain last month, Echodyne lent a helping hand.

Echodyne — a Kirkland, Wash.-based startup backed by Microsoft co-founder Bill Gates — provided the compact radar systems for DARPA’s tests during the week of Oct. 23 in the San Diego area, in conjunction with the University of Washington’s Applied Physics Laboratory.

The Aerial Dragnet exercise involved putting Echodyne’s EchoGuard and EchoFlight flat-panel radar systems on two large tethered aerostat balloons that flew as high as 400 feet, as well as on rooftops and towers around San Diego and National City.

DARPA then sent up several types of drones for the systems to detect and track. A key challenge involved being able to distinguish the drones from other objects in the background, including ground vehicles and birds.
