DIGITIZATION SYSTEMS AND TECHNIQUES AND EXAMPLES OF USE IN FMCW LIDAR METHODS AND APPARATUSES

摘要

Examples are provided that use multiple analog-to-digital converters (ADCs) to disambiguate FMCW ladar range returns from one or more targets that may be greater than the Nyquist frequencies of one or more of the ADCs. Examples are also provided that use a first and a second laser FMCW return signal (e.g., reflected beam) in combination with two or more ADCs to disambiguate one or more target ranges (e.g., distances to one or more objects).
