Abstract
A lidar sensor system. The lidar sensor system includes a transmission unit having a laser source, a phase modulator for modulating a phase of the light of the laser source, and a transmission optic for emitting the modulated light; a reception unit having a reception optic for receiving light reflected from an object and having an evaluation unit for evaluating the light received by the reception optic; the transmission unit being embodied to emit several transmission sequences of the light; each transmission sequence having a first portion and a second portion; the first portion being an unmodulated constant-phase signal; the second portion being a signal phase-modulated by the phase modulator; and the evaluation unit being embodied to determine at least an absolute value of a Doppler frequency based on the first portion, and to determine a distance to the object based on the Doppler frequency and the second portion.
