1. An automatic target detection and scan conversion system for use with radar systems comprising:

  • circuit means for receiving a radar video signal, threshold circuitry for passing only portions of said video signals above a threshold to indicate target reflections, a preprocessor means responsive to the output of said threshold circuitry to generate an output signal when a predetermined number of target reflections occur during selected number of radar antenna scan;

    a final processor means for discriminating between valid target reflections and false alarms for generating an output video signal of the valid target reflections for display, said final processor means including A register means, means for adding a value to said register means upon the occurrence of an output signal from said preprocessor means, means for subtracting a value from said register means if an output signal is not generated from said preprocessor means, and means for sensing when the stored value in said register means exceed a predetermined valve.
