  • Range detector
    Patent number: 4232315
    Abstract: A doppler range detector with early and late range gates responding to radar returns or either side of maximum velocity range and supplying a peak output amplitude when the early and late gates have the same doppler frequency. A peak detector is used to detect slant range with a dual pulse ranging system. The returns are supplied to two zero beat mixers, the output signals of which are passed through separate bandpass filters to a multiplier. The multiplier output is supplied through a low pass filter to the peak detector.
