ABSTRACT:
A frequency-modulated continuous-wave (FM-CW) ranging system produces a first signal of frequency corresponding to the measured range of a target which signal is sometimes below a given quality and produces a second signal of frequency corresponding to the measured range of a simulated target of known range. A threshold detector determines when the target signal is above the given quality at which time the period of the first signal is determined from a given cycle thereof while concurrently the period of the second signal is determined from which the range to the target can be computed.
