Weban algorithm, which can be applied to improve the FMCW range accuracy down to a few mm. Numerical system simula-tions are used to evaluate the possibility of using a combina-tion between an FMCW and a phase radar for a line based range detection at 24 GHz. The history of perimeter protection is based on building . L WebAltimeters commonly use FMCW technology for many reasons, including the ability to measure short distances, high range accuracy, and low power requirements as discussed in [1]. Therefore, this example uses a triangle FMCW waveform. A key processing step for FMCW radar is dechirping.
