Abstract | A method for determining phase information in a radar system comprises receiving a first RF oscillator signal at a first input node and receiving a second RF oscillator signal at a second input node, wherein an arrangement having a multiplicity of delay elements is connected between the first input node and the second input node, and wherein corresponding RF signals representing a superposition of first RF oscillator signal and second RF oscillator signal are present at different positions of the arrangement. The method further comprises generating measurement values representing the amplitudes of the RF signals, generating digital representations of the measurement values, and calculating a relative phase value, representing the difference between the phase of the second RF oscillator signal and the phase of the first RF oscillator signal, on the basis of the digital representations of the measurement values. |
