1. Apparatus for processing applied radar video signals derived from a radar receive to permit the use of a narrow frequency bandwidth data link to a radar display, said apparatus comprising:

  • video extraction means coupled to said radar receiver for removing random pulse interference and noise from the video signals;

    first means coupled to said extraction means for transmitting radar clutter video signals, from preselected azimuth segments at selected time periods;

    memory means coupled to said first means and to said radar display for storing said radar clutter video signals applied thereto and applying said stored signals to said radar display; and

    second means coupled to said video extraction means and said radar display for comparing said radar video signals applied thereto to time-averaged, scan-to-scan radar video signals computed thereby, and for transmitting said radar video signals to said radar display when the difference between the radar video signals and said time-averaged radar video signals is greater than a preselected value.
