1. A pulse present detection system comprising:

  • receiver means for receiving an RF signal and amplifier means for amplifying said RF signal;

    converter means connected to said amplifier means for converting said received RF signal to digital words representing the instantaneous amplitude over selected periodic time increments of said RF signal,detector means having multiple threshold levels in which the digital value of said sampled RF signal is compared to the threshold values,each threshold value having a separate and programmable number of amplitude samples that must occur above said threshold before a pulse presence is declared,each threshold level having a separate reporting means for reporting a separate pulse presence signal, andresolution means for selecting between pulse present signals reported by said threshold levels wherein the first threshold level to report a pulse present is selected.
