Correcting mutual coupling and isolation for a 2-D real-time microwave camera

Recently, new technologies have made it possible to produce synthetic aperture radar (SAR) based microwave images in real-time by using different microwave imaging arrays. However, depending on the imaging array construction the data of interest may be corrupted by mutual coupling and poor isolation. SAR images created from this data have an increased level of artifacts. This paper presents a method for correcting or pre-processing the data by using correlation canceling technique and provides an analysis of three different estimates of the correction. Simulation results show the efficacy of this method, which is corroborated by experiment.
