Abstract
A light detection and ranging (lidar) sensor system may include a laser source configured to generate a beam, an electronic module, and one or more processors. The electronic module may generate, based on the beam, an optical signal that is frequency-shifted by a frequency offset relative to a local oscillator (LO) signal. The electronic module may control a transmitter to transmit the optical signal to an environment. In response to transmitting the optical signal, the electronic module may receive a returned optical signal that is reflected from an object in the environment. The electronic module may generate a digital signal based on the received signal. The electronic module may digitally mix the digital signal based on the frequency offset to generate a sample signal. The one or more processors may determine, based on the sample signal, a range to the object.
