Signal Intelligence

A technique that was pioneered in the 1960s and 1970s called Signals Intelligence (SIGINT) uses high-power radio monitors, remote surveillance, satellite imagery, and radar systems to monitor and detect hostile and illegal activities before and while they unfold. Systems are deployed remotely and backhauled to central monitoring and coordination sites.

Today’s high-performance Signals Intelligence (SIGINT) systems require massive processing power to detect, identify, and classify an enormous number of highly complex signals. SIGINT systems typically consist of a variety of functional elements – signal processors (themselves often consisting of multiple processing elements), snapshot memory buffers, high-speed data recorders, and bulk storage – all residing in multiple physical units, connected through high-speed data pipes. In many application data flows, the processing elements within and between the distinct units need to be interconnected using switched fabrics.
