Multistatic M-sequence UWB Radar System for Microwave Breast Imaging

The design of a multistatic ultra-wideband (UWB) microwave radar imaging system for breast cancer detection is presented in this paper. Based on pseudo-noise code (M-sequence) technology, this multiple-input-multiple-output (MIMO) system includes 24 antennas and records data from 12S channels. Furthermore, it realizes complete rotation of the antenna array around the breast, which allows several options of clutter removal and differential imaging, respectively. The system underwent a first feasibility study on volunteers at University Hospital Jena. The procedure of examination and first experiences are described in this paper.
