Abstract

The present disclosure relates to a light detection and ranging (LIDAR) sensor comprising a detector configured to generate a first detector signal at a first delay time following an emission of a first light pulse and to generate at least one second detector signal at the first delay time following an emission of at least a second light pulse; and a processor configured to generate a combined signal for the first delay time based on a combination of the first detector signal and the at least one second detector signal. Depending on the type of combination, the combined signal can be used for interference detection or mitigation.
