Claim 5:
6. A method comprising:
generating, by a radar sensor, range-gate data representing the position of an object within a region of interest;
performing a first Doppler Fast Fourier Transform (Doppler-FFT) on the range-gate data to provide a first set of Doppler-FFT data, the first set of Doppler-FFT data;
identifying a first velocity associated with a first signal amplitude that exceeds a first noise floor with respect to the first set of Doppler-FFT data;
determining a first correction value for the range-gate data from the identified first velocity;
modifying the range-gate data using the determined first correction value to provide a first set of modified range-gate data;
performing a second Doppler-FFT on the first set of modified range-gate data to provide a second set of Doppler-FFT data;
identifying a second velocity associated with a second signal amplitude that exceeds second noise floor with respect to the second set of Doppler-FFT data;
determining a second correction value for the first set of modified range-gate data from the identified second velocity;
modifying the first set of modified range-gate data using the determined second correction value to provide a second set of modified range-gate data; and
applying a third Doppler-FFT to the second set of modified range-gate data to provide a third set of Doppler-FFT data.
