Abstract
A method and apparatus are provided in which receiver circuitry and signal processing circuitry may reside. The receiver circuitry receives a FMCW radar signal having a content signal (e.g., a random or information signal) embedded into a radar waveform and indicating a relationship in the FMCW radar signal between beat frequency and time delay. The signal processing circuitry may apply a filter (e.g., filtering with a group delay that approximates or relates to the relationship) that causes a residual error in, due to dispersion of, the content signal, and may account for (e.g., mitigate) the residual error by introduction of a dispersion-related function in further processing of the content signal.
