Method for Detecting an Object with a Frequency Modulated Continuous Wave (FMCW) Ranging System

摘要

In a method for detecting an object with an FMCW (frequency modulated continuous wave) ranging system a superior accuracy and resolution is obtained by determining the strongest sinusoidal component in the frequency spectrum and removing the determined component from the spectrum, repeating the preceding step at least once, adding one of the components determined in the two preceding steps to the spectrum, re-determining the then strongest sinusoidal component in the spectrum and removing the re-determined component from the spectrum, repeating the preceding step for each remaining of the determined sinusoidal components, and repeating the last two steps until a desired degree of convergence is reached.
