Space-based Staring Infrared Sensors
The US, in 1970, launched the first of a series of space-based staring array sensors that detected and located infrared heat signatures, typically from rocket motors but also from other intense heat sources. Such signatures, which are associated with measurement of energy and location, are not pictures in the IMINT sense. Currently called the Satellite Early Warning System (SEWS), the program is the descendant of several generations of Defense Support Program (DSP) spacecraft. The USSR/Russian US-KMO spacecraft has been described, by US sources, as having similar capabilities to DSP.
Originally intended to detect the intense heat of an ICBM launch, this system proved useful at a theater level in 1990-1991. It detected the launch of Iraqi Scud missiles in time to give early warning to potential targets.

Famous quotes containing the word staring:
“The body was still resting on its legs, leaning against the end of the side of the bed, while one of the arms was close clasped round the bed-post. The mouth was rigidly closed, but the eyes were open as though staring at him.”
—Anthony Trollope (1815–1882)
