Fremgangsmåde til udnyttelse af Dopplersignaler fra en mikrobölge-Dopplerradar ti bestemmelse af hastigheden hen over jorden

The method involves defining three speed ranges for evaluation of different (overlapping) speed values sampled in parallel with a sampling rate adapted to the respective speed by computer, signal pre-processing, detecting intervals between passing thresholds representing periodic duration of the Doppler signal in all speed ranges, controlling thresholds using the sampling signals, averaging periodic duration values, defining three decision criteria for selecting a speed range and passing determined speed from selected range to higher level evaluation unit. Independent claims are also included for the following: (a) an arrangement with a processor; (b) a computer program product; (c) a computer-readable memory medium.
