  • Patent number: 4743910
    Abstract: Frequency domain, pulse compression CW radar apparatus comprises a frequency synthesizer which provides RF and IF CW signals and linear frequency modulator (LFM) which provides a saw tooth LFM ramp signal with the f.sub.LFM. A mixer combines the f.sub.LFM signal with the f.sub.RF signal to provide a CW radar signal having a frequency, (f.sub.RF +f.sub.LFM) for transmitting by a transmitter. A receiver receives time-delayed CW radar return signals reflected, for example, from clutter at a one range and from a target at another range. A second mixer down-converts the clutter and target return signals to an intermediate frequency for processing and a third mixer extracts the f.sub.LFM signal from the intermediate frequency clutter and target return signals to provide, in a frequency-time domain, rectangular wave, clutter and target signals.
