Abstract
This invention relates to a method for determining at least one of a distance and a relative velocity by means of continuous wave radar measurements. The method includes generating a measurement signal in the form of a continuous wave radar signal; transmitting the measurement signal by means of an antenna (112); reflecting the measurement signal by means of a reflector (118), thereby providing a desired reflected measurement signal; receiving the desired reflected measurement signal; and determining at least one of a distance and a relative velocity between the antenna and the reflector by means of the desired reflected measurement signal. The reflection of the measurement signal involves asymmetrically modulating the measurement signal at the reflector. The determination of at least one of a distance and a relative velocity includes detecting the desired reflected measurement signal among several received reflections of the measurement signal, by means of information added by the asymmetric modulation.
