Fm - cw - radar system having a target object - distance measurement and target object - speed measurement

摘要

A frequency modulated continuous wave radar wherein analog signals received from a target are converted to digital form, processed by correlation with differently delayed signals, also in digital form, of a modulation waveform repetitively applied to the transmitted signals and the frequency spectra of the resulting signals are determined, such spectra being indicative of range of the target. In addition, a digital correlator adapted to perform the desired correlation is shown.
