A light detection and ranging system. The system includes a solid-state optical antenna array, a phase monitor array, a phase controller, a plurality of phase shifters and a global phase shifter. The phase monitor array is configured to output a first mixed signal associated with one of the optical antenna subarrays, and a second mixed signal associated with two of the optical antenna subarrays. The phase controller is configured to output a first phase coefficient based on the first mixed signal and a second phase coefficient based on the second mixed signal. One of the phase shifters is configured to apply the first phase coefficient to compensate for temperature variation within one of the optical antenna subarrays. The global phase shifter is configured to apply the second phase coefficient to compensate for temperature variation between two of the optical antenna subarrays.
