The demonstration took place this summer during a routine flight test of DAS conducted aboard the company's BAC 1-11 test bed aircraft.
'DAS is an omni-directional infrared system that can simultaneously detect and track aircraft and missiles in every direction, with no practical limit on the number of targets it can track."
