Abstract: A coherently working lidar system for capturing the surroundings, which emits a phase-modulated signal, wherein the phase of said signal is produced by switching between discrete values from a sequence of phase values, and the times of the phase switching form a subset of an equidistant time raster. The system receives the signals reflected back from objects and converts the signals into a low-frequency signal by mixing and digitizing them in a receive sequence. The system determines the time shift and frequency shift of signals reflected by objects from said receive sequence. The phase modulation sequence includes two periodically interleaved sequences, wherein the first sequence has constant or periodic phase values and primarily serves to determine the frequency shift, whilst the second sequence substantially changes irregularly between phase values and serves to determine the time shift.
