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.

Abstract: A method for a radar apparatus is described. According to one example implementation, the method involves receiving a multiplicity of chirp echoes from transmitted radar signals and generating a digital signal based on the multiplicity of chirp echoes. In this case, each chirp echo has an associated subsequence of the digital signal. The method further involves performing a filtering in the time domain for one or more subsequences. The filtering in this case involves the decomposition of the subsequence into a plurality of components (referred to as principal components), the selection of a subset of components from the plurality of components and the reconstruction of a modified subsequence based on the selected subset of the component.
