Abstract
Systems and methods are provided for a radar processing chain for frequency-modulated continuous wave radar systems. A transmitter transmits a plurality of chirps, each comprising an electromagnetic radiation signal, at a region of interest. A receiver front-end receives reflected electromagnetic radiation for each chirp and generates a time series of beat-signal samples for each chirp at each antenna of a plurality of antennas. A signal processor detects objects within the region of interest by providing a frequency domain representation of each time series of beat-signal samples as sample values for a set of range bins representing respective distances from the receiver, correcting the sample values for each of the set of range bins to provide a set of clutter corrected samples for each range bin, and determining an angular spectrum for each of a subset of the set of range bins from the clutter corrected samples.
