Abstract
A method for determining a distance between a ranging device and target, wherein a valid interference profile, if already available, is subtracted from a frequency-domain echo profile that is analyzed to determine the distance of the target, where to obtain or update the valid interference profile, a low-frequency portion of the frequency-domain echo profile is stored as a temporary interference profile after each measurement, and if the target is not proximal to the ranging device and the valid interference profile is not available, the temporary interference profile is saved as the valid interference profile, otherwise if the valid interference profile is available, the valid interference profile is updated via the temporary interference profile, otherwise if the target is distal and the valid interference profile is not yet available, the temporary interference profile is first subjected to a quality check before being saved as the valid interference profile.
