1. A lidar calibration system, comprising:
a calibration target comprising a surface having at least one characterized reflectivity, wherein the surface is configured to receive one or more calibration signals emitted by a lidar device along one or more optical axes when the lidar device is separated from the calibration target by an adjustable distance;
at least one lens positioned along the one or more optical axes to modify the one or more calibration signals;
an adjustable attenuator positioned along the one or more optical axes, wherein the adjustable attenuator is configured to attenuate each of the one or more calibration signals to simulate, in combination with the at least one lens, a distance that is greater than the adjustable distance; and
a calibration controller configured to analyze data associated with detected reflections of the one or more calibration signals based on the at least one characterized reflectivity, the adjustable distance, and characteristics of the at least one lens.
