A short-range radar system having a unquie method of processing a linear FM/CW signal so as to provide target range information at the time of target detection. The linear FW/CW signal is mixed with a portion of the transmitted signal and with an intermediate frequency ramp signal to produce a difference frequency signal in the form of a frequency ramp which is a function of the range to the target. The ramp signal is then converted to a pulse which is determinative of the range to the target.
