    en.wikipedia.org/wiki/Early-warning_radar

    An early-warning radar is any radar system used primarily for the long-range detection of its targets, i.e., allowing defences to be alerted as early as possible before the intruder reaches its target, giving the air defences the maximum time in which to operate.

    The Westinghouse radar used a pipelined fast Fourier transform (FFT) to digitally resolve 128 Doppler frequencies, while Hughes's radars used analog filters based on the design for the F-15. Westinghouse's engineering team won this competition by using a programmable 18- bit computer whose software could be modified before each mission.

  9. Erieye - Wikipedia

    en.wikipedia.org/wiki/Erieye

    The Erieye AEW&C mission system radar is an active, phased-array, pulse-doppler sensor that can feed an onboard operator architecture or downlink data, via an associated datalink subsystem, to a ground-based air defence network. The system employs a large aperture, dual-sided antenna array housed in a dorsal 'plank' fairing.
