1. A radar beam sharpening system for processing a radar video stream of echo return intensities, sampled in range and azimuth, comprising:

  • a signal processor configured to apply beam sharpening to the radar video stream and to selectively vary the level of beam sharpening applied to samples of the radar video stream based on their respective ranges so as to generate an output range-dependent beam sharpened radar video stream,wherein the signal processor is configured to reduce the beam sharpening applied for at least a portion of shorter ranges relative to longer ranges.
