This paper deals with adaptive compensation of gain and phase errors possibly present in FMCW radars. To this end, a detailed characterization of the baseband noise and of the useful signal is first obtained. Then, elaborating on existing results, it is shown how to estimate the gain and phase errors and compensate them. A preliminary assessment of the compensation procedure on real data collected by an off-Theshelf transceiver is also given.

Abstract
This paper deals with adaptive compensation of gain and phase errors possibly present in FMCW radars. To this end, a detailed characterization of the baseband noise and of the useful signal is first obtained. Then, elaborating on existing results, it is shown how to estimate the gain and phase errors and compensate them. A preliminary assessment of the compensation procedure on real data collected by an off-Theshelf transceiver is also given.File in questo prodotto:
