  2. Doppler radar - Wikipedia

    en.wikipedia.org/wiki/Doppler_radar

    A Doppler radar is a specialized radar that uses the Doppler effect to produce velocity data about objects at a distance. [1] It does this by bouncing a microwave signal off a desired target and analyzing how the object's motion has altered the frequency of the returned signal.

  3. AN/APQ-116 - Wikipedia

    en.wikipedia.org/wiki/AN/APQ-116

    AN/APQ-115 suffered from inaccurate references (poor stabilization and Doppler inputs), which directly lead to the development of more advanced system such as AN/APQ-122. [ 3 ] The Texas Instruments I-band AN/APQ-116 is a TFR used in A-7 Corsair II [ 1 ] and C-130 Hercules aircraft.

    The AN/SPG-51 is an American tracking / illumination fire-control radar for RIM-24 Tartar and RIM-66 Standard missiles. It is used for target tracking and Surface-to-air missile guidance as part of the Mk. 73 gun and missile director system, which is part of the Tartar Guided Missile Fire Control System.

  6. Space-time adaptive processing - Wikipedia

    en.wikipedia.org/wiki/Space-time_adaptive_processing

    For ground-based radar, cluttered returns tend to be at DC, making them easily discriminated by Moving Target Indication (MTI). [3] Thus, a notch filter at the zero-Doppler bin can be used. [2] Airborne platforms with ownship motion experience relative ground clutter motion dependent on the angle, resulting in angle-Doppler coupling at the ...
