Original Abstract Submitted
example embodiments relate to differential methods for determining environment estimation, lidar impairment detection, and filtering. an example embodiment includes dividing a plurality of lidar device channels into a first group and a second group and interleaving the channels. the embodiment includes applying a threshold to the first group. the embodiment further includes emitting light pulses from a lidar device into an environment surrounding the lidar device, and detecting return light pulses. the return light pulses in the first group of channels are sampled from the signals that exceed the threshold. the embodiment may further include determining a differential in a statistical distribution between the return light pulses in the first group and the return light pulses in the second group. based on the differential, the method can include detecting an atmospheric scattering medium in the environment surrounding the lidar device.
