Novel FMCW radar system concept with adaptive compensation of phase errors M.Vossiek, P. Heide, M. Nalezinski, V. Magori SIEMENS AG - Corporate Research & Development Dept. ZFE T KM 1, D-81730 Munich / Germany Abstract A new high-performance FMCW sensor system concept is presented. The approach is based on an adaptive signal processing scheme compensating phase errors caused by VCO phase noise as

A novel close-range imaging system Birgit Michael and Wolfgang Menzel. University of UIm, Microwave Techniques, D 89069 UIm, Germany. Abstract radar sensors separated by 1 - 2 m is presented for close range imaging. Resolution is achieved via range resolution from the two different sensor positions, exploiting both mono- and bistatic responses, thus give good facilities for multi-target scenarios
