Abstract
A coherent lidar system for capturing the surroundings is configured to emit a phase-modulated signal with pseudo-random change over discrete phase values. The system receives the signals reflected back from objects and converts the signals into a low-frequency signal by mixing and digitizing. The system includes a digital signal processing for correlation filtering of the low-frequency received signal. At least a part of the two-dimensional correlation filter is realized by a hardwired digital circuit embodied as a pipeline, wherein multiple or all of the output values are determined per clock frequency of the digital circuit in one of the two dimensions, and over a sequence of clock frequencies in the other dimension.
