      This paper presents an algorithm for the reduction or removal of the quadrature-receiver phase errors of stepped-frequency frequency-modulated continuous wave (FMCW) imaging systems. The algorithm includes the procedures for the phase error estimation and correction process. Theoretical analysis and simulations are included in the paper to demonstrate the effectiveness of the algorithm.
