Northrop Grumman completed the first test flight of its Vehicle and Dismount Exploitation Radar (VADER) system, a sensor system being developed for use with the Sky Warrior extended-range UAV. When deployed, VADER will allow accurate Ground Moving Target Indicator (GMTI) data and Synthetic Aperture Radar (SAR) imagery to be readily available to ground commanders in real time. During this first test flight conducted in Georgetown, Md., high-resolution SAR imagery and GMTI data were collected on a Northrop Grumman PBN Islander test aircraft and processed on a radar ground station to show vehicle motion on the ground.
