Abstract: A radar system applies various angle correction processes with varying levels of computational overhead to reduce errors in angle estimation when processing received return signals. The various angle correction processes aim to overcome systematic errors affected by range migration through correction based on simulation or hardware measurements, through non-iterative refinement, iterative refinement, and/or a combination of correction and iterative refinement.

Abstract: A Frequency Modulated Continuous Wave (FMCW) radar system is provided that includes a chirp profile storage component configured to store a chirp profile for each chirp of a frame of chirps and a timing engine coupled to the chirp profile storage component to receive each chirp profile in transmission order during transmission of the frame of chirps, in which the timing engine uses each chirp profile to configure a corresponding chirp.
