Abstract : Document describes a method and device for extracting Doppler information from the return signal of an Fm radar system. The range response is shaped and filtered. A single impulse mixer samples the range response at a preselected point of each repetition of a preselected repetition rate. A flat Range Law to a given distance limit can be obtained, with cutoff beyond that distance. (Author)
