Data Collection Supports Sensors Development Published Dec. 4, 2006 By Sensors Directorate AFRL/SN WRIGHT-PATTERSON AIR FORCE BASE, Ohio -- AFRL engineers conducted joint data collection with representatives from the Air Force Institute of Technology, Strategic Communications, and Los Alamos National Laboratory to support development of the Angel Fire airborne electro-optical sensor and the Goals, Objectives, Technical Challenges, and Approaches-based, or " GOTChA," synthetic aperture radar sensor. Angel Fire is a rapid-response program developed to meet a need for a persistent staring reconnaissance capability supporting force protection efforts. GOTChA provides a similar capability using radar sensors with an all-weather/nighttime capability. Angel Fire and GOTChA sensors each collected imagery while monitoring vehicle and pedestrian traffic and several urban warfare scenarios. The team's data collection generated nearly 20 terabytes of radar and optical imagery data, which will support further sensor development efforts.
