Abstract : A frequency modulated continuous wave radar signal is transmitted to a target and the signal reflected from the target is compared with a sample of the continuous wave transmitter to produce a difference frequency signal. The difference frequency signal is band-pass amplified, wide-band limited, and processed by two frequency discriminators displaced from each other in the frequency domain, but both within the frequency band of the limiter and band pass amplifier. Detectors, integrators, and thresholding circuits determine, with suitable false alarm rates, in which half of which discriminator the difference frequency signal is concentrated. (Author)
