Estimation and Correction of Quadrature-Receiver Phase Errors of Stepped-Frequency FMCW Systems for High-Resolution ImagingLiebling, Michael; Lee, Hua; Lee, Michael; Doonan, Daniel; University of California, Santa Barbara (International Foundation for Telemetering, 2012-10)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.
Resolution Analysis and System Integration of a Dynamically Reconfigurable FMCW Medical Ultrasound Imaging SystemLiebling, Michael; Lee, Hua; Lee, Michael; Doonan, Daniel; University of California, Santa Barbara (International Foundation for Telemetering, 2012-10)This paper describes the system performance analysis of the dynamically reconfigurable FMCW medical ultrasound imaging systems. Full-scale resolution analysis, for mono-static, bi-static, and multi-static data-acquisition formats, and laboratory experiment are included in the analysis.
