Abstract

A calibration method for operating a CW short-range radar system in obtaining calibrated intermediate frequency in-phase and quadrature outputs comprises measuring at least one reflective static calibration target at a plurality of at least four different target ranges and processing the received CW radar measurement signal by performing a quadrature downconversion of the received CW radar beam intensity and phase to obtain measured intermediate frequency in-phase outputs and intermediate frequency quadrature outputs. These are used to solve a system of equations for calibration parameter values including an amplitude mismatch a phase mismatch between the quadrature signals, and individual DC offsets of the quadrature signals.
