According to one embodiment, a radar receiving system is provided comprising a first receiving circuit, a second receiving circuit, a spectral analyzer, an object detector, and a phase compensation circuit. The spectral analyzer is configured to generate, from a first plurality of reception signals, a first set of Fourier transformation output values and, from a second plurality of reception signals, a second set of Fourier transformation output values. The object detector is configured to determine a range/Doppler bin of a plurality of range/Doppler bins as an estimate of a range and speed of an object. The phase compensation circuit is configured to determine a phase offset between the Fourier transformation output values of the first set and second set of Fourier transformation output values and to compensate the phases of at least a part of the second set of Fourier transformation output values by the determined phase offset.
