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.
