Abstract:
A method of operation for a radar system that transmits a multiple-slope frequency modulated continuous wave signal and identifies primary frequency components of a baseband signal containing range and range-rate information for targets in a field of view of the radar system, the method comprising the steps of:forming potentially related sets of frequency components by associating potentially related frequency components from like-polarity slopes of the transmitted signal; computing range and range-rate values based on each of the formed sets, and comparing such values to identify those sets of frequency components that are potentially attributable to a given target; combining potentially related sets of the identified frequency components from opposite-polarity slopes of the transmitted signal; computing range and range-rate values for each of the combined sets of frequency components, and identifying combined sets of frequency components that are attributable to the given target as those having a substantially identical range-rate; and attributing the computed range and range-rate of the identified combined sets of frequency components to the given target.
