Since the 1940s, radar development has focused on narrow-beam, scanning sensors. A wide field of view has advantages
in terms of extended acquisition time for any target, and when combined with a high Doppler sampling frequency can
yield high-resolution Doppler spectra. Unambiguous range and Doppler can be achieved under certain circumstances,
resulting in enhanced ability to evaluate the characteristics of targets and clutter. Holographic radar has a range of
applications in which the ability to discriminate targets among clutter is key. An example of such an application is in
mitigation of wind farm interference with Air Traffic Control radar.
